8414479abe [StorageV2] Implement GC
Summary:
Here are some numbers from the benchmark:

```
(TOOLCHAIN) mtomic@poso:~/memgraph/build_release$ tests/benchmark/storage_v2_gc --num-threads 8
Config: NoGc, Time: 25.9836
Config: OnFinishGc, Time: 49.012
Config: 100msPeriodicGc, Time: 45.9856
Config: 1000msPeriodicGc, Time: 40.3094
```

```
(TOOLCHAIN) mtomic@poso:~/memgraph/build_release$ tests/benchmark/storage_v2_gc --num-threads 7
Config: NoGc, Time: 20.4256
Config: OnFinishGc, Time: 39.6669
Config: 100msPeriodicGc, Time: 30.7956
Config: 1000msPeriodicGc, Time: 35.128
```

It is not that bad if there is a core dedicated to doing garbage collection.

5b8e7ff432 Implement edges in storage v2
Summary:
This change implements full edges support in storage v2. Edges can be created
and deleted. Support for detach-deleting vertices is added and regular vertex
deletion verifies existance of edges.

54e1e4e1ff Initial version of storage v2
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.
