* renamed --limit to --include (-i)
* added --exclude (-e)
Kontemplate users can now explicitly include and exclude certain resource sets.
Excludes always override includes.
Closes#11
* Adds support for calling `kubectl replace` (necessary for resource types that do
not support `apply`).
* Sets `kubectl` context to whatever is defined in the cluster configuration file
This integrates support for actually calling out to `kubectl apply`.
A dry-run flag is implemented, too.
The `run` command has been renamed to `template`.
Adds a basic CLI structure with a single "run" command that takes a --file (-f)
and --limit (-l) flag.
--limit can be used to only output certain resource sets.
Closes#4
