Ed25519 ssh keys when adding ActionScript target

When configuring the ActionScript target, the target discovery failed using Ed25519 ssh keys. The error says 'Could not extract key pair elements from provided string’. 

The recommendation within the bank is to Ed25519 ssh keys. When changing to RSA key type, target discovery worked.

As RSA is based on factorial of 2 large primes, the key size is, with the minimum required is 2,048 bit long key – the recommended is 4,096. This poses a couple of issues:

   - Slow computation due to key size

   - Clunkiness on managing such large keys

Yet for Ed25519 type, it is based on Elliptic Curves, and it offers not only  better security, but better performance(the key size is just 256 bit long). RedHat added support for RHEL 7(used on Turbo vm), in 2018.

That said, I’d like to raise a Feature Request to add support for Ed25519 keys on Turbonomic.

    Thanks for raising this. We'll give this some consideration as we look more closely at Workflows and Action orchestration and how we can improve there.
