0c40c67ac2 Implement remote create (storage, RPC, not operator)
Summary:
Implementation of remote vertex and edge creation. This diff addresses
the creation API (`GraphDbAccessor::InsertEdge`,
`GraphDbAccessor::InsertRemoteVertex`) and the necessary RPC and
`RemoteCache` stuff.

What is missing for full remote creation support are
`query::plan::operator` changes that are expected to minor. Pushing this
diff as it's large enough, operator and end to end tests in the next.

Also, the naming of existing structures and files is confusing (update
refering to both updates and created, `results` used too often etc.). I
will address this too, but feel free to comment on bad naming.

9721ccf61c Cleanup per-transaction caches in distributed
Summary:
On the master cleanups are hooked directly into the transaction engine.
This is beneficial because the master might have bigger caches and we
want to clear them as soon as possible.

On the workers there is a periodic RPC call to the master about living
transactions, which takes care of releasing local caches. This is
suboptimal because long transactions will prevent cache GC (like with
data GC). It is however fairly simple.

Note that all cleanup is not done automatically and `RemotePull` has
been reduced accordingly. @msantl, please verify correctness and
consider if the code can be additionally simplified.

f808252142 Prepare RecordAccessor for distributed, part one
Summary:
This diff consolidates local and remote update handling. It ensures and
tests that updates for remote elements are visible locally (on the
updating worker).

The next part will be accumulating remote updates and applying them on
the owner.

Also extracted a common testing fixture.
