Look up handles without listing all resources

[UserNotFound]

We have an API endpoint that allows returning apps and databases for a given handle, or for a a combination of handle and account handle. This is much faster than doing the filtering client side.

Tho illustrates the time it takes to identify an app by handle, I ran aptible config --app httpd in a test account with 400 apps. The performance of the current CLI release is as follows: (real CLI execution time and the response time of the request we're changing)

The same change has been made to databases, as well as accounts.
