Helm had been exposing XDG based variables to end users. This lead
to confusion. For example, if a user wanted to change the cache
location Helm used should they change the XDG variable? Since this
would be like changing the HOME environment variable the answer
is no.
This change adds HELM_*_HOME environment variables to be used
in addition to XDG ones of the same name. Helm will now look
for the Helm specific variable. If not set, Helm will fall
back to XDG locations. If those are not set a default location
will be used. This keeps XDG in use as a default when present,
provides users with the ability to set the location, and removes
XDG from being exposed to end users to avoid confusion.

The completion of charts was using 'helm search repo' which can be
quite slow as it must parse the entire yaml of every repo cache file.
Using completion for a chart name can end up triggering multiple calls
to 'helm search'; this makes the user experience poor, as there is
a delay of over a second at every <TAB> press.
This commit creates a cache file for each repo which contains the list
of charts for that repo. The completion logic then uses this new
cache file directly and obtains the chart names very quickly.
With only the stable repo configured, this optimization makes the
completion of charts about 85 times faster, going from 1.2 seconds to
0.014 seconds; such a difference gives a much better user experience
when completing chart names.
On the other hand, adding the creation of the chart list cache file to
'helm repo update' or 'helm repo add' is pretty much negligible compared
to the downloading of the index file.
It is also worth noting that when more repos are configured,
'helm search repo' only becomes slower, while the completion logic that
uses the new chart list cache file will not be affected as it only looks
for the single relevant repo file.
