If the existing service and checks are the same as the new registration.

agent: ensure node info sync and full sync. (#7189)
This fixes #7020.

There are two problems this PR solves:
  * if the node info changes it is highly likely to get service and check registration permission errors unless those service tokens have node:write. Hopefully services you register don’t have this permission.
  * the timer for a full sync gets reset for every partial sync which means that many partial syncs are preventing a full sync from happening

Instead of syncing node info last, after services and checks, and possibly saving one RPC because it is included in every service sync, I am syncing node info first. It is only ever going to be a single RPC that we are only doing when node info has changed. This way we are guaranteed to sync node info even when something goes wrong with services or checks which is more likely because there are more syncs happening for them.

Paul Banks e812f5516a Add -sidecar-for and new /agent/service/:service_id endpoint (#4691)
- A new endpoint `/v1/agent/service/:service_id` which is a generic way to look up the service for a single instance. The primary value here is that it:
   - **supports hash-based blocking** and so;
   - **replaces `/agent/connect/proxy/:proxy_id`** as the mechanism the built-in proxy uses to read its config.
   - It's not proxy specific and so works for any service.
   - It has a temporary shim to call through to the existing endpoint to preserve current managed proxy config defaulting behaviour until that is removed entirely (tested).
 - The built-in proxy now uses the new endpoint exclusively for it's config
 - The built-in proxy now has a `-sidecar-for` flag that allows the service ID of the _target_ service to be specified, on the condition that there is exactly one "sidecar" proxy (that is one that has `Proxy.DestinationServiceID` set) for the service registered.
 - Several fixes for edge cases for SidecarService
 - A fix for `Alias` checks - when running locally they didn't update their state until some external thing updated the target. If the target service has no checks registered as below, then the alias never made it past critical.

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.

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.
