Prior to the introduction of this configuration, grpc keepalive messages were
sent after 2 hours of inactivity on the stream. This posed issues in various
scenarios where the server-side xds connection balancing was unaware that envoy
instances were uncleanly killed / force-closed, since the connections would
only be cleaned up after ~5 minutes of TCP timeouts occurred. Setting this
config to a 30 second interval with a 20 second timeout ensures that at most,
it should take up to 50 seconds for a dead xds connection to be closed.

Remove outdated usage of "Consul Connect" instead of Consul service mesh.
The connect subsystem in Consul provides Consul's service mesh capabilities.
However, the term "Consul Connect" should not be used as an alternative to
the name "Consul service mesh".

* auto-config: relax node name validation for JWT authorization
This changes the JWT authorization logic to allow all non-whitespace,
non-quote characters when validating node names. Consul had previously
allowed these characters in node names, until this validation was added
to fix a security vulnerability with whitespace/quotes being passed to
the `bexpr` library. This unintentionally broke node names with
characters like `.` which aren't related to this vulnerability.
* Update website/content/docs/agent/config/cli-flags.mdx

Prevent serving TLS via ports.grpc
We remove the ability to run the ports.grpc in TLS mode to avoid
confusion and to simplify configuration. This breaking change
ensures that any user currently using ports.grpc in an encrypted
mode will receive an error message indicating that ports.grpc_tls
must be explicitly used.
The suggested action for these users is to simply swap their ports.grpc
to ports.grpc_tls in the configuration file. If both ports are defined,
or if the user has not configured TLS for grpc, then the error message
will not be printed.
Fix an issue where rpc_hold_timeout was being used as the timeout for non-blocking queries. Users should be able to tune read timeouts without fiddling with rpc_hold_timeout. A new configuration `rpc_read_timeout` is created.
Refactor some implementation from the original PR 11500 to remove the misleading linkage between RPCInfo's timeout (used to retry in case of certain modes of failures) and the client RPC timeouts.
Adds a user-configurable rate limiter to proxycfg snapshot delivery,
with a default limit of 250 updates per second.
This addresses a problem observed in our load testing of Consul
Dataplane where updating a "global" resource such as a wildcard
intention or the proxy-defaults config entry could starve the Raft or
Memberlist goroutines of CPU time, causing general cluster instability.
