Unrecoverable Error: Cannot enqueue Query after fatal error.

[nullstyle]

If a connection is killed by mysql, or the running stex application otherwise gets its connection into a fatal state, stex does not properly recover and the service requires a restart to resume normal function.

Instead, stex needs to validate/reconnect to the db at the HTTP request boundary if no connection is available, and we need to close connections after we receive a fatal error.
