Add a way to provide descriptions for SSH keys

[Jeff Lane ]

I have several SSH keys listed on LP and some of them are older and honestly I'm not sure what machine they apply to now. These have descriptors in them like <name>@ubuntu or similar that don't tell me much about the machine they came from.

Sometimes It's necessary to add new keys from VMs or containers and those sometimes have generic names that don't really provide any context.

Please add the facility to provide short names or descriptions for the keys. It would be a lot easier to read the list of keys with these like this:

Name: Jeff's Laptop
KEy: <KEY DATA>

Name: Home MAAS Server
Key: <KEY DATA>

Name: Development Container
Key: <KEY DATA>

That will help a lot also when it comes time to delete older unused keys.

The key comment only defaults to USER@HOST. You're welcome to change it.
