In #82362 we updated the list of cipher suites to match the "recommended" cipher suites defined in RFC 8447. As noted in that PR, very old clients may fail to connect.
For systems using those very old clients, this PR adds a setting that can be used to re-enable the "old" cipher suites removed in that PR.
Release note (security update): adds option to re-enable "old" cipher suites for use with very old clients.
Release justification: fixes a regression
