3e6137110b Add support for using ssh-agent as a KMS
This adds a new KMS, SSHAgentKMS, which is a KMS to provide signing keys
for issuing ssh certificates signed by a key managed by a ssh-agent. It
uses the golang.org/x/crypto package to get a native Go implementation
to talk to a ssh-agent.

This was primarly written to be able to use gpg-agent to provide the
keys stored in a YubiKeys openpgp interface, but can be used for other
setups like proxying a ssh-agent over network.

That way the signing key for ssh certificates can be kept in a
"sign-only" hsm.

This code was written for my employer Intinor AB, but for simplicity
sake gifted to me to contribute upstream.

With this change the default management key is not required as the
