This PR introduces an environment variable to enable multiplexed sessions for read-write transactions, batch write and partition operations.
This feature is currently opt-in and can be enabled by:
GOOGLE_CLOUD_SPANNER_MULTIPLEXED_SESSIONS_FOR_RWto true to enable for read-write transactions and batch write .GOOGLE_CLOUD_SPANNER_MULTIPLEXED_SESSIONS_PARTITIONED_OPSto true for partition operations.GOOGLE_CLOUD_SPANNER_MULTIPLEXED_SESSIONSto true (mandatory). TheGOOGLE_CLOUD_SPANNER_MULTIPLEXED_SESSIONS_FOR_RWorGOOGLE_CLOUD_SPANNER_MULTIPLEXED_SESSIONS_PARTITIONED_OPSsetting will have no effect unless this variable is also set to true.
