Template paths were relative to the chart that contained them, which
meant that all templates were named 'template/SOMETHING'. This made it
trivially easy to hit namespace collisions as in #933.
Template path names are essentially opaque strings so this patch simply
changes them to be qualified by parent chart.
This allows templates to access information about the template file.
Right now, the template can only access the .Template.Name, which is the
chart-relative path to the current template.
Closes#894
Instead of printing "no value", this prints an empty string by
default, but adds a Strict flag on the engine, which (if true)
will cause a template render to error out if a value is not supplied.
Strict is set to false so that developers can instead use `default` to
set default values.
This commit finally ties `helm install` together with the Kubernetes
client library to make an end-to-end trip.
There were several small fixes to go on both client and server side,
along with some changes to proto to support better error reporting.
The alpine chart has been updated to exhibit how the new Helm works.
