fix flush deadlock

This commit fixes a deadlock that occurs during b1 flushes. It's
caused by taking locks in a different order. In the flush, b1
locks the engine and then bolt. However, in the query cursor, a
lock is obtained on bolt first (via `DB.Begin()`) and then the
engine is locked while reading from the engine's cache.

Fixed issue where pre-install script would attempt to copy to a non-e…

Fix race in cluster RPC serialization

Point was accessed from multiple goroutines and there was a race on the the internal
cachedFields and cachedName fields.  Accessing these fields is unnecessary work as it
requires the point to be unmarshal into Go types and then remarshaled back into protbuf
types.  Instead, just send the line protocol version already available on the point via
the protobuf.  This avoid accesssing these cached fields and eliminates some extra work.

Possible fix for influxdata#4069
