example of cache file

kubernetes-charts-cache.yaml

This is what a cache file will look like:
Under the name-version key, we'll specificy a url to actually download the chart, 
a created timestamp, a removed boolean field, and a dump of the Chart.yaml file which includes the keywords.

You can use the keywords and the name fields for the search command.
Cache files are currently located under HELM_HOME/cache and named in the repoName-cache.yaml format. 
FYI: The directory structure under helm home will change so that the directory is safe for people who are migrating 
from the old helm tool. The new structure will look like this HELM_HOME/repository/cache/ (I'm moving all of 
the stuff in HELM_HOME currently under a directory called `repository`.)
