* Fix up REPLICA GetInfo and CreateSnapshot
Subtle bug where these actions were using the incorrect transactional
access while in REPLICA role. This casued timestamp to be incorrectly
bumped, breaking REPLICA from doing replication.
* Delay DNS resolution
Rather than resolve at endpoint creation, we will instread resolve only
on Socket connect. This allows k8s deployments to change their IP during
pod restarts.
* Minor sonarsource fixes

Summary:
Edge filters (edge type and destination vertex) are now handled natively in the
storage API. The API is implemented to be the fastest possible when using the
filters with the assumption that the number of edge types will be small.

Summary:
Previously, when accessing the labels/properties/edges of a vertex/edge that
was just created the NEW view would correctly display the change, but the OLD
view would be invalid and would crash the database. With this change the OLD
view of a freshly created vertex/edge won't cause a crash, but will instead
report an error.

Summary:
Initial implementation of new storage engine. It implements snapshot isolation
for transactions. All changes in the database are stored as deltas instead of
making full copies. Currently, the storage supports full transaction
functionality (commit, abort, command advancement). Also, support has been
implemented only for vertices that have only labels.
