server: remove config entry CAS in legacy intention API bridge code (#9151)
Change so line-item intention edits via the API are handled via the state store instead of via CAS operations.

Fixes #9143

Add a paramter in state store methods to indicate whether a resource insertion is from a snapshot restoration (#9156)
The Catalog, Config Entry, KV and Session resources potentially re-validate the input as its coming in. We need to prevent snapshot restoration failures due to missing namespaces or namespaces that are being deleted in enterprise.

If they are sent to EventPublisher.Publish.

Also document that PayloadEvents is expected to come from a subscription and that it is
not immutable.

state: ensure we unblock intentions queries upon the upgrade to config entries (#9062)
1. do a state store query to list intentions as the agent would do over in `agent/proxycfg` backing `agent/xds`
2. upgrade the database and do a fresh `service-intentions` config entry write
3. the blocking query inside of the agent cache in (1) doesn't notice (2)

Daniel Nephin 61ce0964a4 stream: remove Event.Key
Makes Payload a type with FilterByKey so that Payloads can implement
filtering by key. With this approach we don't need to expose a Namespace
field on Event, and we don't need to invest micro formats or require a
bunch of code to be aware of exactly how the key field is encoded.

Daniel Nephin 8ef4c0fcc5 state: use go-cmp for comparison
The output of the previous assertions made it impossible to debug the tests without code changes.

With go-cmp comparing the entire slice we can see the full diffs making it easier to debug failures.

Daniel Nephin f9b2834171 state: convert the remaining functions to ReadTxn
Required also converting some of the transaction functions to WriteTxn
because TxnRO() called the same helper as TxnRW.

This change allows us to return a memdb.Txn for read-only txn instead of
wrapping them with state.txn.

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.

server: create new memdb table for storing system metadata (#8703)
This adds a new very tiny memdb table and corresponding raft operation
for updating a very small effective map[string]string collection of
"system metadata". This can persistently record a fact about the Consul
state machine itself.

The first use of this feature will come in a later PR.

Daniel Nephin 6e592ec485 state: rename and export EventPayload
The subscribe endpoint needs to be able to inspect the payload to filter
events, and convert them into the protobuf types.

Use the protobuf CatalogOp type for the operation field, for now. In the
future if we end up with multiple interfaces we should be able to remove
the protobuf dependency by changing this to an int32 and adding a test
for the mapping between the values.

Make the value of the payload a concrete type instead of interface{}. We
can create other payloads for other event types.
