Daniel Nephin 242b3a2dc5 streaming: set a default timeout
The blocking query backend sets the default value on the server side.
The streaming backend does not using blocking queries, so we must set the timeout on
the client.

Daniel Nephin bc4d349ccf streaming: support X-Cache-Hit header
If a value was already available in the local view the request is considered a cache hit.
If the materialized had to wait for a value, it is considered a cache miss.

Daniel Nephin 3d5ff8b5db submatview: add test cases for store.Get with timeout and no index
Also set a more unique name for the serviceRequest.Type to prevent potential name conflicts
in the future.

Daniel Nephin 23e1cd6f93 submatview: only return materializer from getEntry
Also rename it to readEntry now that it doesn't return the entire entry. Based on feedback
in PR review, the full entry is not used by the caller, and accessing the fields wouldn't be
safe outside the lock, so it is safer to return only the Materializer

Daniel Nephin 4fb2ba9de7 submatview: move error return to NewMaterializer
So that we don't have to create views ahead of time, when we will never use that view.

api: ensure v1/health/ingress/:service endpoint works properly when streaming is enabled (#9967)
The streaming cache type for service health has no way to handle v1/health/ingress/:service queries as there is no equivalent topic that would return the appropriate data.

Ensure that attempts to use this endpoint will use the old cache-type for now so that they return appropriate data when streaming is enabled.

Daniel Nephin f40b76af2d proxycfg: use rpcclient/health.Client instead of passing around cache name
This should allow us to swap out the implementation with something other
than `agent/cache` without making further code changes.

Daniel Nephin d5cc206e39 streaming: move ServiceTag and NodeMetaFiltering to the cache-entry
So that all the client side filtering is in the same place. Previously
only the bexpr filter was in the cache-entry.

Also makes a small change to the filtering so that instead of rebuilding
slices of items, the filtering can return a bool to determine if the
event payload is saved or not.

Pierre Souchay 5bee19ee16 Do not filter tags unless req.TagFilter is set
Send empty array [] instead of [""] in DNS requests when TagFilter is not set

Do not change case sensitivity of services anymore in `getServiceNodes()` since
cache keys are now case insensitive

Daniel Nephin 529f252d5c rpcclient: Add health.Client and use it in http and dns
This new package provides a client agent implementation of an interface
for fetching the health of services.

This approach has a number of benefits:

1. It provides a much more explicit interface. Instead of everything
   dependency on `RPC()` and `Cache.Get()` for many unrelated things
   they can depend on a type that are named according to the behaviour
   it provides.

2. It gives us a single place to vary the behaviour and migrate to
   a new form of RPC (gRPC). The current implementation has two options
   (cache, or direct RPC), and in the future we will have more.
   It is also a great opporunity to start adding `context.Context` args
   to these operations, which in the future will allow us to cancel
   the operations.

3. As a concequence of the first, in the Server agent where we make
   these calls we can replace the current in-memory RPC calls with
   a thin adapter for the real method. This removes the `net/rpc`
   machinery from the call in places where it is not needed.

This new package is quite small right now, but I think we can expect it
to grow to a more reasonable size as other RPC calls are replaced.

This change also happens to replace two very similar implementations with
a single implementation.
