WIP: my work towards the update API (#6) for service accounts

[SSmale]

I tried to use a service account and ran into issues, I saw #3 and #6 so thought I would give it a go, I had never written go so it is a but touch, but is a starting point if someone else wants to puck it up further.

the drafts dir has the 2 tf files I had written.

Issues:

• need to run create the service account first then run a normal apply
• need a better way to add the email address as it was trying to add it each time it ran
• to delete, you need to remove the DNS record, not sure how you would link out to something else to destroy it
• url encoding/decoding was fun, it doesn't give it to you in a way you could give it back
• you still need to manually add it to your search console, it is just pre-verified

I also wrote a blog post about what I need to do to get this all to work
