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.

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.

Summary:
This makes Gid the same as the one in storage/v2. Before they can be
merge into one implementation, we probably want to have a similar
transition for remaining ID types.
Depends on D2346

Micro benchmarks show some minor variations compared to the previous
commit. Smaller cases are a bit worse while larger data cases are a bit
better.

Summary:
Micro benchmarks show improvements in performance of MapLiteral from 5%
to 40% depending on the size of the input. On the other hand, a sequence
of AdditionOperators behaves the same with both allocation schemes.

The global variable may hide the fact that it uses the default
utils::NewDeleteResource() for allocations.

Summary:
`dump()` awesome Memgraph function is removed.
`mg_dump` executable now uses "dump database" command instead of "return dump()"
and dumps database to standard output instead of a file.

Stream queries to the output table.
For effective output streaming, a simple operator, `OutputTableStream` is implemented which fetches and
produces a single row on each Pull.

Summary:
This diff only introduces a MemoryResource member to TypedValue and correctly
propagates through various constructors and assignments. At the moment,
MemoryResource is not used to actually allocate anything.
