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.
