Create a UI to let the user publish his public keys that will be stored on the SSH KeyStore. (See example from Github on the attachments)

On https://issues.jboss.org/browse/AF-1217 mstevens1_jira provided a mock for this UI (https://rawgit.com/srambach/BxMS-frontend/setting-tabbed/spaces-settings.html)

This UI must have the following features:

• show the existing user Public keys, also it should display when the key was added and the last time used.
• abiltiy to add new Public keys and store them on the actual SSH KeyStore. It should validate that the key is valid before adding the key into the SSH KeyStore
• ability to remove any of the existing keys
