[#64396444] Initial take at Proxy config in PAT

Added a proxy configuration dialog, logic to verify proxy configuration
and prompt for password if necessary and set the proxy configuration
globally.

Todo:

 - More robust checking of proxy settings
 - Pass settings to AWS ruby script

[#64396444] Proxy settings working and passed to all components

Currently not working: any uri unfriendly characters which are in a user name

The patch is to come in a future commit.
