Summary:
Currently, when starting Memgraph with the production package (DEB/RPM),
Memgraph always outputs an error for not being able to replace an existing
query module (`example.so` with `example.c`). This diff introduces a precheck
so that the error message is correct - so that Memgraph doesn't try to replace
an `.so` file with a `.c` file before verifying that the `.c` file is a valid
query module (which it obviously isn't). Also, I have moved the source of the
example into a subdirectory so that it isn't even considered while loading
modules.

Summary:
With this diff, each build of Memgraph has a version that uniquely identifies
it. The given version uniquely identifies both official release builds and
development builds. Enterprise/community builds are also differentiated in the
version. Also, support for custom suffixes is added to support custom builds
for customers.

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.
