…che#495) Allow configuring the connect timeout via `connectTimeoutMs` so that the driver doesn't wait so long before giving up on unreachable locations. Fixes apache#494.

## What's Changed Instead of repeatedly trying to access locations which have failed before, cache them and move them to the end of the list of locations to attempt on subsequent accesses. This provides a better user experience for Flight SQL services that return multiple locations in the expectation that the user may not be able to access some of them (but would have a better experience if they are). Requires apache#494. Closes apache#661.
