Summary:
It doesn't make sense to tie skipping a member for serialization to a
particular serialization implementation.

Summary:
With quite frequent changes of serialization backend, it's getting
really painful updating the C++ implementation. This diff defines the
Symbol class via LCP, so that the C++ serialization is generated instead
of written by hand.

Instantiation with VertexAccessor was never used, so the template

Summary:
TypeInfo will be needed for upcoming serialization via SLK. This diff
changes the already defined TypeInfo by removing the reliance on
capnp::typeId calls. The struct itself is now in utils.
Hopefully, this shouldn't break our RPC stack due to new ID generation.

Summary:
This is the initial work on transferring our serialization code from
Cap'n Proto to SaveLoadKit. The commit contains tests for generated
code, but still requires work on supporting some features. Most notably,
generating and storing type IDs for derived classes so that they can be
loaded from a base pointer. Naturally, loading implementation hasn't
even been started yet.

GraphDb now has GetStorageStat method that returns live view to
object containing vertex_count, edge_count and avg_degree().
Stat is updated on each garbage collection run and represents number of
objects that are visible to any transaction.

Since we need to send `StateDelta`s over the wire in HA, we need to be

Summary:
This change makes HierarchicalTreeVisitor visit only Cypher related AST
nodes. QueryVisitor can be used to differentiate between various query
types we have. The next step is to either rename HierarchicalTreeVisitor
to something like CypherQueryVisitor, or perhaps extract Clause visiting
from it.

Summary:
Generate conversion functions from C++ enum to Cap'n Proto and vice
verse. This should reduce the generated code size and hopefully improve
readability.
Use conversion functions for enums in default serialization generation.
`capnp-save-enum` and `capnp-load-enum` should now be used exclusively
to serialize non LCP defined enumerations. They now always require
`enum-values` argument.
