`snap` should provide functionality to find packages with needed plug or connector

snapd (Ubuntu)

Bug Description

Steps to reproduce:
1. Install any supported Ubuntu version
2. Try to use `snap` command to find packages with needed plug or connector

Expected results:
* snap has functionality to find packages with needed plug or connector

Actual results:
* snap do not have functionality to find packages with needed plug or connector

the problem is actual because of the fact that user will not know about supported plugs or connector until he/she install the snap (see https://askubuntu.com/q/1046585/66509 and https://askubuntu.com/q/1034030/66509 ) . For example it is hard to find Snap package with `:removable-media` plug or connector. Snapcart.io does not have this functionality (see https://github.com/canonical-websites/snapcraft.io/issues/642 ) .
