Merge lp:~cmars/juju-core/1.18-resolve-cs-series into lp:juju-core/1.18

[Casey Marshall]

Ported r2559 from trunk to 1.18

For the deploy and upgradecharm commands, when a series is not provided, and a
default-series is not set in the environment config, the client will resolve
the series with the charm store, through the state server. If the client is
working with a 1.16 state server, it will resolve the series directly with the
charm store.

Existing environments will have a default-series, so they should have no
change in series selection.

New environments will continue to support the default-series config setting,
but it can be omitted, and is not set by default.

This is a cherry-pick of r2559 from trunk.

Original trunk proposal, for context:

PTAL & thanks,

Cherry pick looks ok.
Only reviewed for obvious backporting errors as original work was
approved.
