Summary:
All mgp_* symbols are exported from Memgraph executable, no other
symbols should be visible.
The primary C API header, mg_procedure.h, is now part of the
installation. Also, added a shippable query module example.
Directory `query_modules` is meant to contain sources of modules we
write and ship as part of the installation. Currently, there's only an
example module, but there may be potentially more. Some modules could
only be installed as part of the enterprise release.
For Memgraph to load custom procedures, it needs to be started with a
flag pointing to a directory with compiled shared libraries implementing
those procedures.

Summary:
This makes the concrete memory resource an explicit argument in custom
procedures. Unfortunately, the API is a bit uglier but at least we don't
have to worry about threading, global state or similar. This is the
primary reason for this change as we would probably like to allow
procedures to spawn threads to compute stuff in a parallel fashion.

Summary:
The `mg_value` is the main data type used in upcoming custom procedures. Each
custom procedure will receive arguments as an array of `mg_value` instances.
The results of custom procedures will also be built as `mg_value` instances.
We should strive to have as simple and straightforward C API for custom
procedures, because we want to limit the possibility of errors and bugs on the
user facing side. Custom procedures will run in Memgraph and as such can cause
crashes and potentially a lot of nasty stuff. The burden is on the writer of
custom procedures not to mess things up, so we should make messing things up
from the C API hard if not impossible to do.
