ActionCable protocol negotiation

In particular, the fact that ApplicationController is the only
one inheriting from AC::API is not a default. You could say at
most that generators generate them that way, but the creation
of controllers is something which is out of our control because
programmers write controllers by hand.

Instead, we can say that normally, conventionally, as in the
majority of Rails apps, that is the actually the case.

This is primarily for backwards compatibility for when
or if the protocol is changed in future versions.

If the server fails to respond with an acceptable
protocol, the client disconnects and disables
the monitor.

Move `quoted_date`, `quote_string` and `quote_table_name_for_assignment` methods to `Quoting` module
