ref(*) move lib code into pkg

feat(*): stub out commands for helm

Feat/deploy

Also removed the now unused deploy subpackage and fixed the makefile
accordingly.

fix(dm): correct error in status code check

Implement client side of `helm deploy`

Couple of copyright fixes.

fix(create): do not use full path for chart name

Fix expandybird build and expansion failures

Update stale template links

This re-jiggers the deployment to use common.Configuration. Right
now it will not work, since the remote server expects a common.Template
instead of a common.Configuration. Still trying to figure out which
side to change.

add helm-dm charts proposal to dm docs

Add LoadData() for server-side reading.
