f63a5e9de5 Rename PluginRegistry to ModuleRegistry 
Summary:
The registry is now in the `query::procedure` namespace, this makes the
naming more consistent. I.e. we are dealing with custom procedure which
are contained in modules. This naming convention is similar to Python
source code where each file represents a module and each module provides
multiple functions (or procedures in our case). At the moment we only
support exactly 1 procedure per module, but the openCypher syntax allows
for more.

04c037e0fd Add PluginRegistry for openCypher custom procedures 
Summary:
This diff implements a mechanism for registering plugins which provide
custom procedures for openCypher. Although the `Plugin` struct already
stores some function pointers, these are not set in stone w.r.t. to
requirements and signatures.

For example, in the future, we may want to allow a single plugin to
register multiple custom procedures instead of just one.
