This updates the command to our emergent standards. It also enables
using a separate config file for a config kms, which allows non-string
values to be encrypted.
This allowed some nice cleanup as well.
This can be used in tests to get access to a controller that behaves
just like a dev controller but doesn't require the normal Command bits
(UI, etc).
This can be enhanced over time as needed; for now it's pretty simple but
it's good enough to be used for API tests. A simple project create/read
API test is added as well, which serves to show the programmatic model
(as well as test those functions at the API level).
These changes create a dev org in the database on startup.
They also plumb through a dev-org-id flag that allows specifying a chosen org ID in dev mode.
The logic will allow us to let people specify a default org ID in the config file too, although currently that's not enabled.
Several other improvements were made as well:
* Consolidation of some code from across the server commands
* Plumbing shutdownch through so we can use it for canceling contexts during startup
This was copied from Vault code but shouldn't be necessary any more as a
change in hclog a while back meant that derived loggers share the log
level of the parent.
