Add support for ssh commit signing (#17743)

Browse source 
* Add support for ssh commit signing

* Split out ssh verification to separate file

* Show ssh key fingerprint on commit page

* Update sshsig lib

* Make sure we verify against correct namespace

* Add ssh public key verification via ssh signatures

When adding a public ssh key also validate that this user actually
owns the key by signing a token with the private key.

* Remove some gpg references and make verify key optional

* Fix spaces indentation

* Update options/locale/locale_en-US.ini
