freddygv a1c1e36be7 Allow cross-partition references in disco chain
* Add partition fields to targets like service route destinations
* Update validation to prevent cross-DC + cross-partition references
* Handle partitions when reading config entries for disco chain
* Encode partition in compiled targets

freddygv 02fb323652 Rename partition-exports to exported-services
Using a name less tied to partitions gives us more flexibility to use
this config entry in OSS for exports between datacenters/meshes.

when only one field is used.

freddygv feaebde1f1 Remove useInDatacenter from disco chain requests
useInDatacenter was used to determine whether the mesh gateway mode of
the upstream should be returned in the discovery chain target. This
commit makes it so that the mesh gateway mode is returned every time,
and it is up to the caller to decide whether mesh gateways should be
watched or used.

freddygv c3e381b4c1 Rename service-exports to partition-exports
Existing config entries prefixed by service- are specific to individual
services. Since this config entry applies to partitions it is being
renamed.

Additionally, the Partition label was changed to Name because using
Partition at the top-level and in the enterprise meta was leading to the
enterprise meta partition being dropped by msgpack.

Rename "cluster" config entry to "mesh" (#10127)
This config entry is being renamed primarily because in k8s the name
cluster could be confusing given that the config entry applies across
federated datacenters.

Additionally, this config entry will only apply to Consul as a service
mesh, so the more generic "cluster" name is not needed.

Daniel Nephin 51ad94360b state: move ConfigEntryKindName
Previously this type was defined in structs, but unlike the other types in structs this type

an API type, but part of the state implementation.

Daniel Nephin 45f0afcbf4 structs: Fix printing of IDs
These types are used as values (not pointers) in other structs. Using a pointer receiver causes
problems when the value is printed. fmt will not call the String method if it is passed a value
and the String method has a pointer receiver. By using a value receiver the correct string is printed.

Also remove some unused methods.

connect: intentions are now managed as a new config entry kind "service-intentions" (#8834)
- Upgrade the ConfigEntry.ListAll RPC to be kind-aware so that older
copies of consul will not see new config entries it doesn't understand
replicate down.

- Add shim conversion code so that the old API/CLI method of interacting
with intentions will continue to work so long as none of these are
edited via config entry endpoints. Almost all of the read-only APIs will
continue to function indefinitely.

- Add new APIs that operate on individual intentions without IDs so that
the UI doesn't need to implement CAS operations.

- Add a new serf feature flag indicating support for
intentions-as-config-entries.

- The old line-item intentions way of interacting with the state store
will transparently flip between the legacy memdb table and the config
entry representations so that readers will never see a hiccup during
migration where the results are incomplete. It uses a piece of system
metadata to control the flip.

- The primary datacenter will begin migrating intentions into config
entries on startup once all servers in the datacenter are on a version
of Consul with the intentions-as-config-entries feature flag. When it is
complete the old state store representations will be cleared. We also
record a piece of system metadata indicating this has occurred. We use
this metadata to skip ALL of this code the next time the leader starts
up.

- The secondary datacenters continue to run the old intentions
replicator until all servers in the secondary DC and primary DC support
intentions-as-config-entries (via serf flag). Once this condition it met
the old intentions replicator ceases.

- The secondary datacenters replicate the new config entries as they are
migrated in the primary. When they detect that the primary has zeroed
it's old state store table it waits until all config entries up to that
point are replicated and then zeroes its own copy of the old state store
table. We also record a piece of system metadata indicating this has
occurred. We use this metadata to skip ALL of this code the next time
the leader starts up.

connect: fix bug in preventing some namespaced config entry modifications (#8601)
Whenever an upsert/deletion of a config entry happens, within the open
state store transaction we speculatively test compile all discovery
chains that may be affected by the pending modification to verify that
the write would not create an erroneous scenario (such as splitting
traffic to a subset that did not exist).

If a single discovery chain evaluation references two config entries
with the same kind and name in different namespaces then sometimes the
upsert/deletion would be falsely rejected. It does not appear as though
this bug would've let invalid writes through to the state store so the
correction does not require a cleanup phase.

connect: use stronger validation that ingress gateways have compatible protocols defined for their upstreams (#8470)
Fixes #8466

Since Consul 1.8.0 there was a bug in how ingress gateway protocol
compatibility was enforced. At the point in time that an ingress-gateway
config entry was modified the discovery chain for each upstream was
checked to ensure the ingress gateway protocol matched. Unfortunately
future modifications of other config entries were not validated against
existing ingress-gateway definitions, such as:

1. create tcp ingress-gateway pointing to 'api' (ok)
2. create service-defaults for 'api' setting protocol=http (worked, but not ok)
3. create service-splitter or service-router for 'api' (worked, but caused an agent panic)

If you were to do these in a different order, it would fail without a
crash:

1. create service-defaults for 'api' setting protocol=http (ok)
2. create service-splitter or service-router for 'api' (ok)
3. create tcp ingress-gateway pointing to 'api' (fail with message about
   protocol mismatch)

This PR introduces the missing validation. The two new behaviors are:

1. create tcp ingress-gateway pointing to 'api' (ok)
2. (NEW) create service-defaults for 'api' setting protocol=http ("ok" for back compat)
3. (NEW) create service-splitter or service-router for 'api' (fail with
   message about protocol mismatch)

In consideration for any existing users that may be inadvertently be
falling into item (2) above, that is now officiall a valid configuration
to be in. For anyone falling into item (3) above while you cannot use
the API to manufacture that scenario anymore, anyone that has old (now
bad) data will still be able to have the agent use them just enough to
generate a new agent/proxycfg error message rather than a panic.
Unfortunately we just don't have enough information to properly fix the
config entries.

Daniel Nephin 3fcb2e16f4 state: un-method funcs that don't use their receiver
This change was mostly automated with the following

First generate a list of functions with:

  git grep -o 'Store) \([^(]\+\)(tx \*txn' ./agent/consul/state | awk '{print $2}' | grep -o '^[^(]\+'

Then the list was curated a bit with trial/error to remove and add funcs
as necessary.

Finally the replacement was done with:

  dir=agent/consul/state
  file=${1-funcnames}

  while read fn; do
    echo "$fn"
    sed -i -e "s/(s \*Store) $fn(/$fn(/" $dir/*.go
    sed -i -e "s/s\.$fn(/$fn(/" $dir/*.go
    sed -i -e "s/s\.store\.$fn(/$fn(/" $dir/*.go
  done < $file
