PCBC-869: Implemented changePassword for management API (#55, #56)

PCBC-891: Append extension version info to HELLO indentifier (#58)

Increase required PHP version up to 8.0 (#76)

PCBC-890: Scope must implement ScopeInterface (#57)

PCBC-899: Ensure the connection will be closed on error (#70)

PCBC-900: Don’t set "function" property on exceptions. (#74)

PCBC-907: Assign meta to view query result (#79)

Fix missing header for GCC 13 (#63)

CXXCBC-275: Update implementation query context fields passed to the server. In future versions of the server versions it will become mandatory to specify context of the statement (bucket, scope and collection). This change ensures that both future and current server releases supported transparently.

CXXCBC-296: Force PLAIN SASL auth if TLS enabled. Using SCRAM SASL mechanisms over TLS protocol is unnecesary complication, that slows down initial connection bootstrap and potentially limits server ability to improve security and evolve credentials management.

CXXCBC-295: The get with projections opration should not fail if one of the the paths is missing in the document, because the semantics is "get the partial document" and not "get individual fields" like in lookup_in operation.

CXXCBC-294: In the Public API, if get operation requested to return expiry time, zero expiry should not be interpreted as absolute expiry timestamp (zero seconds from UNIX epoch), but rather as absense of the expiry.

CXXCBC-291: Allow to disable mutation tokens for Key/Value mutations (use enable_mutation_tokens in connection string).
