Obliterate STRALGO! add LCS (which only works on keys) (#9799)

Drop the STRALGO command, now LCS is a command of its own and it only works on keys (not input strings).
The motivation is that STRALGO's syntax was really messed-up...
- assumes all (future) string algorithms will take similar arguments
- mixes command that takes keys and one that doesn't in the same command.
- make it nearly impossible to expose the right key spec in COMMAND INFO (issues cluster clients)
- hard for cluster clients to determine the key names (firstkey, lastkey, etc)
- hard for ACL / flags (is it a read command?)

This is a breaking change.
