When Alternator is enabled over HTTPS - by setting the
"alternator_https_port" option - it needs to know some SSL-related options,
most importantly where to pick up the certificate and key.
Before this patch, we used the "server_encryption_options" option for that.
However, this was a mistake: Although it sounds like these are the "server's
options", in fact prior to Alternator this option was only used when
communicating with other servers - i.e., connections between Scylla nodes.
For CQL connections with the client, we used a different option -
"client_encryption_options".
This patch introduces a third option "alternator_encryption_options", which
controls only Alternator's HTTPS server. Making it separate from the
existing CQL "client_encryption_options" allows both Alternator and CQL to
be active at the same time but with different certificates (if the user
so wishes).
For backward compatibility, we temporarily continue to allow
server_encryption_options to control the Alternator HTTPS server if
alternator_encryption_options is not specified. However, this generates
a warning in the log, urging the user to switch. This temporary workaround
should be removed in a future version.
This patch also:
1. fixes the test run code (which has an "--https" option to test over
https) to use the new name of the option.
2. Adds documentation of the new option in alternator.md and protocols.md -
previously the information on how to control the location of the
certificate was missing from these documents.
Fixes #7204.

Scylla developer documentation
This folder (and its subfolders) contain developer-oriented documentation concerning the Scylla codebase. We also have a wiki, which contains additional developer-oriented documentation. There is currently no clear definition of what goes where, so when looking for something be sure to check both.
Seastar documentation can be found here.
User documentation can be found on docs.scylladb.com
