Description

2.x speculative retry params are case insensitive, while 3.0 and 3.11 have added case sensitivity. As as result of this, one of our internal applications suffered an issue during
C* upgrade from 2.x to 3.0.

This ticket is to propose making 3.0 and 3.11 speculative_retry params case insensitive as well (essentially a slightly modified backport of CASSANDRA-13876, but not to allow something like "99p" which 4.0 allows)
