Reduce SessionState size better with MessagePack + LZ4 (#632)
* Encode sessions with MsgPack + LZ4 Assumes ciphers are now mandatory per #414. Cookie & Redis sessions can fallback to V5 style JSON in error cases. TODO: session_state.go unit tests & new unit tests for Legacy fallback scenarios. * Only compress encoded sessions with Cookie Store * Cleanup msgpack + lz4 error handling * Change NewBase64Cipher to take in an existing Cipher * Add msgpack & lz4 session state tests * Add required options for oauthproxy tests More aggressively assert.NoError on all validation.Validate(opts) calls to enforce legal options in all our tests. Add additional NoError checks wherever error return values were ignored. * Remove support for uncompressed session state fields * Improve error verbosity & add session state tests * Ensure all marshalled sessions are valid Invalid CFB decryptions can result in garbage data that 1/100 times might cause message pack unmarshal to not fail and instead return an empty session. This adds more rigor to make sure legacy sessions cause appropriate errors. * Add tests for legacy V5 session decoding Refactor common legacy JSON test cases to a legacy helpers area under session store tests. * Make ValidateSession a struct method & add CHANGELOG entry * Improve SessionState error & comments verbosity * Move legacy session test helpers to sessions pkg Placing these helpers under the sessions pkg removed all the circular import uses in housing it under the session store area. * Improve SignatureAuthenticator test helper formatting * Make redis.legacyV5DecodeSession internal * Make LegacyV5TestCase test table public for linter

## Important Notes

||||
|
||||
- [#632](https://github.com/oauth2-proxy/oauth2-proxy/pull/632) There is backwards compatibility to sessions from v5
|
||||
- Any unencrypted sessions from before v5 that only contained a Username & Email will trigger a reauthentication
