This adds an action to the API that allows pulling out an activation
token that can be given to a worker in its config (directly or via env
or file). The worker can pass this along with its normal request in
place of its normal nonce and the server will automatically accept it.

This stores worker connection nonces within the database to ensure
uniqueness of connections. Prior the connection required any attacker to
be able to decrypt the incoming encrypted authentication message in
order to replay (and if the attacker has access to the KMS you have
bigger problems), but with this change even if an attacker does have
access to the KMS key, they cannot reuse the same message. (If they're
able to encrypt against the KMS key, they can still act as a worker with
a new message, so this only really helps if they only have decryption
capabilities.)
Because of listing visibility, if no actions are assigned to a user for
an individual resource, it's excluded from the list. This is fine and
good. However, when we made a change in 0.2.0 to restrict the
information returned from listing for the anonymous user for scopes and
auth methods, it exposed the fact that because of the way this
visibility works we had to add `read` to scopes by default -- thereby
rather defeating the purpose of restricting what goes back to `u_anon`
requests.
The purpose of "no-op" is to never be used for real actions within the
API, but as something that can be granted to specifically enable
visibility for the targeted user. This makes the controls over list
visibility much more granular.
* Sessions support for read:self and cancel:self permissions. This is automatic with fallback; no API change is needed.
* Strips out values from listing if only self actions are allowed on the resource and the user ID is different. This prevents a default ACL of id=*;type=session;actions=read:self,cancel:self from causing all values to be visible when listing.
* Adds an unprivileged user to development/testing instances. This user has only default permissions plus the ability to authorize sessions in the default target.
* Remove list:self from main
As per futher discussions, we won't be supporting this, in favor of
simply read:self and cancel:self (since listing now already filters out
items on which you have no permissions).
This doesn't remove list:self entirely from the code base as much of
that will simply be converted to read:self and cancel:self -- that will
be in a later PR. However, with this removed if we want to release we
won't expose an API publicly that isn't going to stick around.
It's a bit overwhelming to consume the site and see that you have to
understand all these models. This simplifies it a bit. I also fixed up
some minor wording here and there.
