API documentation: https://docs.couchbase.com/sdk-api/couchbase-c-client-3.0.5

• CCBC-1307: allow to select any mechanisms for SASL regardless network protocol being used.
  But by default, try to avoid downgrading to PLAIN on non-TLS connections. Also the change allows to specify list of
  preferred mechanisms instead of only one (use comma in the value of sasl_mech_force connection string option).
• CCBC-1276: allow to hint flex index usage in query options
• CCBC-1312: fix return values for lcb_cmdquery_scope_*
• CCBC-1313: replace std::random_shuffle with std::shuffle (fixes build of cbc-n1qlback tool)
