* Add tests demonstrating bug #4793: Close() sets sessions=nil without mutex
These tests demonstrate the race condition where Close() sets c.sessions
to nil without holding the mutex, while AcquireSession() tries to access
the map with the mutex held.
Running with -race detects the data race and the test panics with
"assignment to entry in nil map".

* Fix#4793: Protect sessions map access with mutex in Close()
Acquire sessionsMutex before setting sessions to nil in Close() to prevent
data race with AcquireSession(). Also add nil check in AcquireSession() to
handle the case where Close() has been called.
This prevents the panic "assignment to entry in nil map" when Close() and
AcquireSession() are called concurrently.

STEAMPIPE_CACHE environment variable resolves to service cache enabled as well as client cache enabled
service cache enabled is used by the plugin manager to enable/disable caching on the plugins during startup (runtime toggle is not allowed) - with a max_ttl
client cache enabled is used to enable/disable the cache on the database connection (fdw)
A TTL can also be set on the client side capped to max_ttl on the server
