Merge lp:~mthaddon/mojo/charm-testing-initial into lp:mojo/mojo-specs

[Tom Haddon]

If we specify INITIAL_CHARM env variable and use MOJO_MANIFEST_FILE of manifest-initial, start with that charm.

This can be useful for testing new series, for instance - we can create a new version of the charm to test with and do our initial deploy with that rather than the upstream version.
