Add support for the manual provider.

Add support for the manual provider.

Also reorder the provider fields so
that required ones come first.
The hope for this is to improve the
user experience while creating
environments.

Tests: `make check`.

QA: use quickstart as usual to set up
environments.
To test the manual provider, I've done
the following:

- I used a separate vmware virtual machine:
  let's assume its address is 192.168.1.5.
- Install the SSH server in the vm:
        `sudo apt-get install ssh`.
- Copy your ssh credential over:
        `scp -rp ~/.ssh 192.168.1.5:~`.
- Allow sudo power without password for your user on the vm, by
  editing the /etc/sudoers file and adding the following:
        $USER ALL=(ALL) NOPASSWD: ALL
  where $USER is your user name.
- Run `.venv/bin/python juju-quickstart -i`, select the option to
  create a new "Manual Provisioning" environment, select a name for it and
  use the vm address as the "bootstrap host", save the environment
  and then run it!
- wait for the environment to be ready, then run quickstart again
  with the same environment to check it recognizes it's
  already bootstrapped.
Done, thank you!

Please take a look.

LGTM and will QA. Ideally it would be cool if our QA instructions were using
guimaas to just bring up notes and then hook them into juju.

ugh, I think this is going away soon. I'll ping wallyworld and see if it's in
1.21. If that's true it might be worth just waiting a few weeks for 1.21 and
skipping this.

looks like the removal of provider storage won't be in 1.21 so ignore that hope
of not needing it.

QA: 

I used a digital ocean droplet

- created droplet with my ssh key
- had to ssh root@xxx to login and set an initial root password
- added the 'ocean' envirnoment using juju-quickstart -i
- failed at first as it said no tools for my environment so I retired with
--upload-tools
- that ran and worked, gui loaded up in a new window for me
- reran quickstart and it worked and loaded the gui window again for me. Really
pretty quick <3

So my one QA question is if we should always upload tools? I guess I'm on
1.21-beta1 so maybe it's that vs the manual provider. Never mind.

LGTM, no QA.  THanks for this!
