* Port over some SP v2 bits
Specifically:
* Add too-large handling to Physical (Consul only for now)
* Contextify some identity funcs
* Update SP protos
* Add size limiting to inmem storage
* Merge entities during unseal only on the primary
* Add another guard check
* Add perf standby to the check
* Make primary to not differ from case-insensitivity status w.r.t secondaries
* Ensure mutual exclusivity between loading and invalidations
* Both primary and secondaries won't persist during startup and invalidations
* Allow primary to persist when loading case sensitively
* Using core.perfStandby
* Add a tweak in core for testing
* Address review feedback
* update memdb but not storage in secondaries
* Wire all the things directly do mergeEntity
* Fix persist behavior
* Address review feedback
* Merge Identity Entities if two claim the same alias
Past bugs/race conditions meant two entities could be created each
claiming the same alias. There are planned longer term fixes for this
(outside of the race condition being fixed in 0.10.4) that involve
changing the data model, but this is an immediate workaround that has
the same net effect: if two entities claim the same alias, assume they
were created due to this race condition and merge them.
In this situation, also automatically merge policies so we don't lose
e.g. RGPs.
