c8a63861ae refactor main: Move to Kingpin CLI library
Replace urfave/cli with the kingpin[1] library.

It has slightly more sensible argument validation than the other Go libraries.

Additionally I've opted for removing the '-f / --file' flag in favour of positional arguments to commands.

A previous command like `kontemplate template -f somefile.yml` is now just `kontemplate template somefile.yml`. All other arguments remain the same.

32ca64c50a feat templater: Warn if no valid resource sets are included
After filtering resource sets, check whether any resource sets "survived".

Otherwise it can be assumed that the user specified invalid exclude/include
combinations and should be warned about that.

Fixes #35

11cfc80020 feat context: Support resource set default values
This adds functionality to specify default values directly in resource sets.

The idea is that users can create a file called `values.yaml` or `values.json`
in a resource set's folder and have all variables specified in that file be
automatically merged into the resource set variables with the lowest priority.

This fixes #25
This fixes #30 (to a degree)

4eadb58841 fix main: Don't panic if file is unspecified
Instead of printing a spooky stacktrace when the user forgets to specify
the `-f` argument, return an error a lot more gracefully.

3b0f41e71d feat templater: Fail if values are missing
Golang's template package now has an option for failing if template variables
are missing: https://golang.org/pkg/text/template/#Template.Option

This updates the templater code to make use of that option and return the
errors encountered during templating.

This fixes #1

0147c3e13e feat ctx: Let sub-resource-sets inherit vars from parent
Users of kontemplate may expect variables defined on the parent resource to be
inherited by children.

This implements that functionality. Values defined twice are overwritten by the
child's definition.

2f6e008121 feat templater: Add 'pass' lookup function
This introduces support for looking up secret values in the 'pass' command line
tool (https://www.passwordstore.org/).

Values like passwords can be interpolated from pass and even more complex
structures like certificates for Kubernetes Secrets can be retrieved and base64-
encoded as necessary.

4e8223ef34 feat context: Add support for resource set collections
A resource set collection is a resource set with an addition 'include' array
configured. It is a short-hand for importing multiple resource sets from the
same folder and for excluding/including them as a group.

See https://github.com/tazjin/kontemplate/issues/9 for more information.

Closes #9

* renamed --limit to --include (-i)
* added --exclude (-e)

Kontemplate users can now explicitly include and exclude certain resource sets.
Excludes always override includes.

25f2a1616c feat template: Add additional template functions
This adds the Go template functions from [sprig][] as well as a custom `json`
function that can interpolate any data as a JSON object - very useful for adding
arrays of data in JSON format into a variable:

```
certificateDomains:
  - oslo.pub
  - tazj.in

annotations:
  acme/certificate: {{ .certificateDomains | json }}

annotations:
  acme/certificate: ["oslo.pub", "tazj.in"]
```
