GOCBC-1400: Add missing connection string timeout parsing

Motivation
----------
We allow users to specify timeouts in the connection string, however
we are missing some fields - most noticeably kv timeouts.

Changes
--------
Update connection string parsing to parse kv_timeout,
kv_durable_timeout, kv_scan_timeout, and management_timeout.
