Code review comment for lp:~axwalk/juju-core/manual-bootstrap

If the only remaining contentious point is (Has)BootstrapStorage(r),
then I call dealer's choice and LGTM whatever he picks; I don't think
any of the names are great, but I also don't think any of them are so
bad as to unacceptably reduce the quality of the codebase ;).

If there are other problems, carry on as usual, ofc, but let's not block
this on naming arguments.
