age-plugin support

[Kranzes]

Age recently exposed their plugins API as public which allows using it to add Age plugins support to Sops. With these changes which I have no written and don't understand I was able to get age plugins working in Sops. I'd like if someone that knows Go and the codebase continues these changes, as from what I understood a lot of them are just copied over from age itself (?).

I guess a new age release would be still a blocker for this, but review could already happen before that, so by the time we have an age update, this can be merged.

You have to go through this process before anyone looks at your commit probably: https://github.com/getsops/sops/pull/1335/checks?check_run_id=18181524828

Check again if I did it correctly

Looks better now.

Hi.
If someone install "https://github.com/remko/age-plugin-se" and use it only on macos it is fine.

But then i want do something on linux:

$ sops updatekeys ./secrets-db.yaml

error updating one or more master keys: 
  [failed to encrypt new data key with master key "age1se1qd0ljv856qg8chyesxdqw04n9fatp9qwvng6kkzwahr700rjqrq4gh99vdr": 
    failed to create writer for encrypting sops data key with age: 
      failed to wrap key for recipient #0: 
        se plugin: couldn't start plugin: exec: "age-plugin-se": 
          executable file not found in $PATH]

age-plugin-se - is only for macos. Not possible to install on linux!

Soo this error blocks me from adding the newkey (standard/classic age key) from Linux.

Honestly, I am kinda interested in rops more right now and I think I will implement or help implement age-plugin support for it. Don't expect me to continue working on this PR, I don't know Go.

@Kranzes same issue can happen there :)

Your problem stems from the Go code written as part of this PR, it is not inherent to age plugin support for sops/rops, right?
