Less complex branched data error messages.
Improved comprehensibility of database availability logging.

- We no longer use a counter for boot-strap availability, instead components
  mark themselves as blocking during startup, which means they will be included
  in the description of why the database is unavailable during startup.

Fix a memory leak in RerferenceCache

The leak was caused by the fact that when inserting new data in the cache
noone is cleaning up the old GCed values still present in the cache.
Indeed the cleanup was triggered only by updating existing node which have
been GCed or at some extend by getting GCed values.

This PR also tries to improve the polling when during get/remove by looking
to the whole queue instead of just removing the single element.

Fix state bug from upgrading a shared lock using tryExclusive()

If a shared lock is held when sharedExclusive was called, the local lock
state in the client would not be updated properly, instead the call would
return early from this code path. It should have continued the loop to acquire
locks, and it should have updated the local lock map state.

Now it does, this appears to have been a copy-paste error.

Make Cypher not introduce eagerness in some trivially decidable cases

In particular, we do not want the plan for:

```MATCH a, b CREATE (a)-[r:X]->(b)```

to contain an EagerPipe.
