* Added the ability to pass timeout settings from cmd/uplink to libuplink. * Removed commented out code. * Updated 2min timeouts for the uplink CLI. * Removed comment. * Made transport defaultDialTimeout and defaultRequestTimeout public * Added comments to describe where these defaults apply. * Added a new defaults to libuplink and added tests. * Added a new defaults to libuplink and added tests.
