Summary:
The test is now more strict than before. Each verification step doesn't just
verify that object counts are correct, it now also verifies that all object IDs
are correct. The continuous integration script is improved to have a more
deterministic startup.

Summary:
The property store stores a map of `PropertyId` to `PropertyValue` mappings. It
compresses all of the values in order to use as little memory as possible.

Summary:
This diff does not fix our Louvain implementation completely. The algorithm
internally still optimzies the wrong function, but this will at least correctly
calculate the modularity value at the end.
Fix of the algorithm will come in a separate diff

Summary:
Most of the examples require properties to be enabled on edges so this change
specifies that flag explicitly. Also, errors are handled better by replacing
`bolt_client` with `mg_client`. Missing indices are created to improve import
speed.

Summary:
The configuration file that was used for the Debian/CentOS package was manually
written. This diff adds a configuration file generator that extracts all of the
necessary information about the flags directly from the built binary and uses
that information to generate the configuration file for the packages.

Summary:
Don't use flag files for specifying flag values in tests. Instead, all
necessary flags are explicitly defined in each of the tests.

Summary:
The garbage collector had a race condition when it would delete deltas that
were in the middle of an object's delta chain. In the process of deleting
(unlinking) the delta, the garbage collector previously wouldn't acquire any
locks. That operation was then racing with the standard MVCC
`CreateAndLinkDelta` function that adds a new delta into the chain.
Fortunately, `CreateAndLinkDelta` always does its modifications while holding a
lock to the owner of the chain (either a vertex or an edge) so this change just
adds the lock acquiring to the garbage collector.

Summary:
The functions that previously had locks in them are always called while the
vertex lock is already being held. Also, the lock guards were implemented
incorrectly.

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:
This diff renames `__reload__` procedure to be `mg.reload` accepting a
module name. The main CallCustomProcedure function is now split into
multiple parts, so that there's more control over finding a procedure,
type checking its arguments and finally checking the returned result
set.
