Deprecate S2278 in favor of S5547

RSPEC-2278 was specific to DES and TripleDES cipher algorithms, but these are not the only ciphers that are unsecure and not recommended.

RSPEC-5547 the goal of this new RSPEC is to have a more generic rule that catch all the unsecure ciphers we could identify, like DES, TripleDES, RC2, RC4, BlowFish ect
