Fix connection Close hanging if CLIENT REPLY is set to OFF or SKIP. This includes a rework of how command actions are handled to use a single map lookup based on generated permutations to improve performance and allow it to be used in both activeConn and conn. Replication of this lookup is need as its impossible to share information between the different Conn interface implementations due to returning interface instead of concrete type. The performance improvements, 33-89% sec/op and eliminating all memory allocations, help to mitigate the impact of double lookup. This also expands the benchmark coverage to allow for wider validation of this change.

Add support for newer command which impact the state of a client connection hence need special handling when returning connections to the pool. Also add missing type assertions for ConnWithContext on connection types.
