fix(glide.yaml): fix moved gocloud repository

fix(helm): warn on init when Tiller already exists

Looks like another Go git repo got moved around.

fix(ci): disable running coverage in parallel

Previously, if 'helm init' was run on a cluster that had Tiller
installed, the init would fail. However, this condition indicates that
both the client and the server are in a condition to work, so this
should not be an error. This PR downgrades that error to a warning.

Closes #1041

Running in parallel will crash a circle ci node. Disabling until we can
build in some safeguards.

fix(cmd): s/specifiy/specify/

First cut of adding dynamic cluster support to status command

feat(storage): in-memory & configmaps driver

feat(*): implement helm upgrade + upgrade hooks

docs(developers): recommend minikube

fix(git): ignore _dist directory

This reflects our internal decision to suggest minikube rather than
commit resources to maintaining scripts/local-cluster.sh

Closes #889

Serve charts from specified local repository path

fix(helm): fix inspect command to not panic

fix(helm): fix helmignore evaluation of dirs
