Daniel Nephin d9b8d30cad cache: log a warning when Cache.Notify handles an error
Without these warnings, errors are silently ignored, which can make
debugging problems more challenging.

Daniel Nephin 97a577502d config: improve the interface of Load
This commit reduces the interface to Load() a bit, in preparation for
unexporting NewBuilder and having everything call Load.

The three arguments are reduced to a single argument by moving the other
two into the options struct.

The three return values are reduced to two by moving the RuntimeConfig
and Warnings into a LoadResult struct.

Daniel Nephin 2294793357 agent/grpc: use router.Manager to handle the rebalance
The router.Manager is already rebalancing servers for other connection pools, so it can call into our resolver to do the same.
This change allows us to remove the serf dependency from resolverBuilder, and remove Datacenter from the config.

Also revert the change to refreshServerRebalanceTimer

Daniel Nephin bad4d3ff7c grpc: redeuce dependencies, unexport, and add godoc
Rename GRPCClient to ClientConnPool. This type appears to be more of a
conn pool than a client. The clients receive the connections from this
pool.

Reduce some dependencies by adjusting the interface baoundaries.

Remove the need to create a second slice of Servers, just to pick one and throw the rest away.

Unexport serverResolver, it is not used outside the package.

Use a RWMutex for ServerResolverBuilder, some locking is read-only.

Add more godoc.

Daniel Nephin cdd392d77f agent/consul: pass dependencies directly from agent
In an upcoming change we will need to pass a grpc.ClientConnPool from
BaseDeps into Server. While looking at that change I noticed all of the
existing consulOption fields are already on BaseDeps.

Instead of duplicating the fields, we can create a struct used by
agent/consul, and use that struct in BaseDeps. This allows us to pass
along dependencies without translating them into different
representations.

I also looked at moving all of BaseDeps in agent/consul, however that
created some circular imports. Resolving those cycles wouldn't be too
bad (it was only an error in agent/consul being imported from
cache-types), however this change seems a little better by starting to
introduce some structure to BaseDeps.

This change is also a small step in reducing the scope of Agent.

Also remove some constants that were only used by tests, and move the
relevant comment to where the live configuration is set.

Removed some validation from NewServer and NewClient, as these are not
really runtime errors. They would be code errors, which will cause a
panic anyway, so no reason to handle them specially here.

Daniel Nephin 330be5b740 agent/token: Move token persistence out of agent
And into token.Store. This change isolates any awareness of token
persistence in a single place.

It is a small step in allowing Agent.New to accept its dependencies.

Merge of auto-config and auto-encrypt code (#8523)
auto-encrypt is now handled as a special case of auto-config.

This also is moving all the cert-monitor code into the auto-config package.

Daniel Nephin f2373a5575 logging: move init of grpclog
This line initializes global state. Moving it out of the constructor and closer to where logging
is setup helps keep related things together.

Daniel Nephin 33c401a16e logging: Setup accept io.Writer instead of []io.Writer

Daniel Nephin 63bad36de7 testing: disable global metrics sink in tests
This might be better handled by allowing configuration for the InMemSink interval and retail, and disabling
the global. For now this is a smaller change to remove the goroutine leak caused by tests because go-metrics
does not provide any way of shutting down the global goroutine.

Daniel Nephin 5d4df54296 agent: extract dependency creation from New
With this change, Agent.New() accepts many of the dependencies instead
of creating them in New. Accepting fully constructed dependencies from
a constructor makes the type easier to test, and easier to change.

There are still a number of dependencies created in Start() which can
be addressed in a follow up.
