In docs/protocols.md, describing the protocols used by Scylla's (both
inter-node protocols and client-facing protocols), add a paragraph about
the ability to inspect most of these protocols, including Scylla's internal
inter-node protocol, using wireshark. Link to Piotr Sarna's recent blog post
about how to do this.

In commit da3bf20e71 we supposedly enabled
support for Cassandra's "start_native_transport" option which can be set to
0 to run Scylla without listening on the CQL port. This can be useful, for
example, if a user only want the DynamoDB or Redis APIs but not CQL.
Unfortunately, the option was still marked "Unused", so it wasn't really
enabled as a valid command line option. This patch fixes that, and
documents the start_native_transport option in docs/protocols.md, where
we document the different protocols, ports, and options to configure them.
Fixes#6387.

This patch adds a new document, docs/protocols.md, about all the different
protocols which Scylla supports - and the different ports which they use.
This includes Scylla's internal protocol, user-facing protocols (CQL, Thrift,
DynamoDB, Redis, JMX) and things inbetween (REST API, Prometheus).
I wrote this document after being frustrated that when I see a port number
(e.g., "7000") or a port option name (e.g., "storage_port") it's hard to
figure out what they actually are - or why they are given such strange
names. The intention is that this file can easily be searched for option
names, for more familiar names (e.g., "CQL"), and a reader can get the
whole story - including some pointers to relevant part of the code (this
part of the document can be improved further - in this version this only
exists for the internal protocol).
