`ILogger` support for the REST & RPC drivers

[ProphetLamb]

The database drivers DatabaseRest and DatabaseRpc should have a property, initialized from .ctor of the type ILogger Logger.

LoggerMessages should be defined using the LoggerMessageGenerator.

The content, for each logging level, should be reasonable. Here are a few examples:

Verbosity	Example
Debug	Each public method call. e.g. Query, SignUp. The query itself, such as credentials, must never be logged!
Info	Significant state changed Open, Close.
Warning	Duplicate call to open, empty results etc.
Error	Exceptions, failed to open etc.

These are mostly how I personally feel about logging verbosity, feel free to choose differently, within reason.
