Daniel Nephin dcf80907a9 structs: fix cache keys
So that requests are cached properly, and the cache does not return the wrong data for a
request.

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

connect: support defining intentions using layer 7 criteria (#8839)
Extend Consul’s intentions model to allow for request-based access control enforcement for HTTP-like protocols in addition to the existing connection-based enforcement for unspecified protocols (e.g. tcp).

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.

R.B. Boyer 72a515f5ec
connect: various changes to make namespaces for intentions work more like for other subsystems (#8194)
Highlights:

- add new endpoint to query for intentions by exact match

- using this endpoint from the CLI instead of the dump+filter approach

- enforcing that OSS can only read/write intentions with a SourceNS or
  DestinationNS field of "default".

- preexisting OSS intentions with now-invalid namespace fields will
  delete those intentions on initial election or for wildcard namespaces
  an attempt will be made to downgrade them to "default" unless one
  exists.

- also allow the '-namespace' CLI arg on all of the intention subcommands

- update lots of docs

Daniel Nephin b9e4544ec3 intentions: fix a bug in Intention.SetHash
Found using staticcheck.

binary.Write does not accept int types without a size. The error from binary.Write was ignored, so we never saw this error. Casting the data to uint64 produces a correct hash.

Also deprecate the Default{Addr,Port} fields, and prevent them from being encoded. These fields will always be empty and are not used.
Removing these would break backwards compatibility, so they are left in place for now.

Daniel Nephin ea6c2b2adc ci: Add staticcheck and fix most errors
Three of the checks are temporarily disabled to limit the size of the
diff, and allow us to enable all the other checks in CI.

In a follow up we can fix the issues reported by the other checks one
at a time, and enable them.

Intentions ACL enforcement updates (#7028)
* Renamed structs.IntentionWildcard to structs.WildcardSpecifier

* Refactor ACL Config

Get rid of remnants of enterprise only renaming.

Add a WildcardName field for specifying what string should be used to indicate a wildcard.

* Add wildcard support in the ACL package

For read operations they can call anyAllowed to determine if any read access to the given resource would be granted.

For write operations they can call allAllowed to ensure that write access is granted to everything.

* Make v1/agent/connect/authorize namespace aware

* Update intention ACL enforcement

This also changes how intention:read is granted. Before the Intention.List RPC would allow viewing an intention if the token had intention:read on the destination. However Intention.Match allowed viewing if access was allowed for either the source or dest side. Now Intention.List and Intention.Get fall in line with Intention.Matches previous behavior.

Due to this being done a few different places ACL enforcement for a singular intention is now done with the CanRead and CanWrite methods on the intention itself.

* Refactor Intention.Apply to make things easier to follow.
