feat(engine): add 'partial' function

fix(helm): rename --reuse-name to --replace

Add name-template flag for installation that allows the user to specify a template used for release name generation

This adds a context-aware template function called 'partial' that will
allow rendering other templates in a chart into a string value, which
can then be piped to other functions. Usage is something like
'{{partial 'path/to/template.yaml' | indent 2}}'

This might be a bad idea.

Templates can now access the non-template files in a chart by using
the '{{.Files}}' map inside of a template.
