perf: remove session pool#751
Merged

Conversation
The underlying session pool has been completely removed from the driver, and the driver always using a single multiplexed session for all operations. The `min_sessions` and `max_sessions` connection properties are deprecated, and setting a value for either of these has no effect. Note that the driver was already using a single multiplexed session for all operations by default before this change, but had a fallback option to use a session pool. This fallback option is no longer available. This means that the driver also does not need to create and maintain the sessions in the pool. See https://docs.cloud.google.com/spanner/docs/sessions#multiplexed_sessions for more information on multiplexed sessions in Spanner.
