fix(helm): Fake tillerHost at version cmd tests

Fix typo

fix typo

Fix typo

When using pkg/helm as a third party client, I am using chartutil.LoadArchive()
to load a chart from an io.Reader. After that is loaded I wish to install/update that
chart, however InstallRelease and UpdateRelease only accepts a path rather than
something of type *chart.Chart. This adds a new function called InstallReleaseFromChart
which allows one to load a chart separate from the path, then install said chart.

fix doc typo in FAQ

Version cmd tries to set up a tunnel at RunE instead of using the
PersistentPreRunE. That means that for each version test (3) it
tries to set up the tunnel. When running the tests on an internetless
or whithout a valid k8s environment, the tunnel will fail with a
timeout of 20 seconds, meaning that it will take 60 seconds to
run the test.

This commit adds a fake tillerHost so it will not try to setup the
tunnel.
