Frank Schroeder cfc8bd092f local state: refactor TestAgentAntiEntropy_EnableTagOverride
Make intent clearer by being more explicit and adding some comments.
Use verify.Values to compare service entries.

Frank Schroeder b288c1eb9b local state: fix TestAgentAntiEntropy_EnableTagOverride
The test had a race condition where it relied on the first service to be
synced to the remote catalog which sometimes failed.

Frank Schroeder f43972fdc2 local state: drop retry loops from tests
Since the tests are now using synchronous calls for state syncing
we no longer need to use retry loops to wait for the changes to
propagate.

Frank Schroeder 3d10312cd6 agent: skip non-sensical TestCatalogRegister

Frank Schroeder 2bef1d4d51 local state: fix anti-entropy state tests
The anti-entropy tests relied on the side-effect of the StartSync()
method to perform a full sync instead of a partial sync. This lead to
multiple anti-entropy go routines being started unnecessary retry loops.

This change changes the behavior to perform synchronous full syncs when
necessary removing the need for all of the time.Sleep and most of the
retry loops.

Frank Schroeder 60095484c4 local state: replace multi-map state with structs
The state of the service and health check records was spread out over
multiple maps guarded by a single lock. Access to the maps has to happen
in a coordinated effort and the tests often violated this which made
them brittle and racy.

This patch replaces the multiple maps with a single one for both checks
and services to make the code less fragile.

This is also necessary since moving the local state into its own package
creates circular dependencies for the tests. To avoid this the tests can
no longer access internal data structures which they should not be doing
in the first place.

The tests still don't compile but this is a ncessary step in that
direction.

Frank Schroeder ef9aa6b3b6 local state: move to separate package
This patch moves the local state to a separate package to further
decouple it from the agent code.

The code compiles but the tests do not yet.

Frank Schroeder 034ee43cef agent: decouple anti-entropy from local state
The anti-entropy code manages background synchronizations of the local
state on a regular basis or on demand when either the state has changed
or a new consul server has been added.

This patch moves the anti-entropy code into its own package and
decouples it from the local state code since they are performing
two different functions.

To simplify code-review this revision does not make any optimizations,
renames or refactorings. This will happen in subsequent commits.
