feat(2196): secrets management 

feat(helm):Allow remote values.yaml with -f

feat(helm): Add --node-selectors, --override and --output flags to helm init

This feature enables users to specify more control over where Tiller pod
lands by allowing "node-selectors" to be specified. Alternatively, the
"--output" flag will skip install and dump Tiller's raw Deployment manifest to stdout so user may alter it as they see fit (probably with a JSON manipulation tool like jq).

fix(helm): invoking getterConstructor returns downstream error now

>0.0.0-a does not match pre-releases on 0.0.0 that start with a
capital letter or number. This has to do with the ordering of
code points. Numbers and capital letters come before lowercase
letters.

>0.0.0-0 should match all valid pre-releases on 0.0.0. According
to the spec, "Numeric identifiers MUST NOT include leading zeroes."
A 0 is also the lowest code point for all the allowed characters
in a pre-release
