9cffd3d1d4 refactor templater: Add explicit note about empty-rs warnings
Due to an interesting combination of an error not being handled and Go
initialising everything with what it thinks should be the default,
non-existent resource sets have been gracefully handled already.

This makes this accidental fix explicit.

Fixes #90

68e2f99062 feat templater: Add IP lookup function
This introduces support for looking up IP addresses using local DNS resolver.

Function will return a list of all IP addresses associated with hostname.
Further processing can be achieved using supported list template functions.

b20bc5f57a fix templater: Don't template default.yml files
After the change from #84 default variable files with the '.yml'
extension got templated as resource set templates accidentally.

This resolves the issue by moving the list reserved default file names
to a common place and reusing it in both the templater and context pkg.

This fixes #85

063a3e9d30 fix context: Support ".yml" extension on default files
In other places in Kontemplate that deal with YAML files, both the
".yaml" and ".yml" extension are supported.

This fixes context loading code to support that for resource set
variables, too.

This fixes #83

Version 1.2.0
This release comes with some new features, usability improvements and
a better build & release process.

Features:

* Documentation has been improved significantly, check out the new
  [README][] and follow the links within!
* Extra variables can now be loaded from files on disk. Simply specify
  a list of YAML/JSON files under the 'import' key in your cluster
  context file. Check out #66 for details!
* Resource set paths can now be overridden by users. By default it is
  assumed that the path to a resource set is the same as its name,
  however this is now user-controllable.
  This means the same resource set can be included multiple times
  under different names, for easier including/excluding. See #71 for
  details!
* Kontemplate is currently getting a website that is under construction
  at [kontemplate.works][] - feel free to check it out and
  [give feedback][]!

Fixes:

* Windows release binaries now have the correct filename
* Several potential warning and error messages have been improved

Release binaries are signed with GPG key `66F505681DB8F43B` which is
verified on my Github profile.

If a resource set is specified by the user and does _not_ contain any
templates, a warning will now be printed.

e8cfa9c119 refactor build: Keep GPG-signatures outside of tarballs
Instead of signing the binary and adding the signature in the release
tarball, keep the GPG-signatures *outside* of the tarball.

This makes it easier to use the built-in GPG-signature verification
features of package managers such as pacman.

Vincent Ambo
7607f6dc0f feat context: Allow overriding resource set paths
Instead of always inferring the path at which files in a resource set
are located, let users override the path by specifying a `path` field.

This makes it possible to add the same resource set multiple times
with different values while still keeping distinct names for
addressability (for example when using include/exclude).

This fixes #70

e2be6152f9 chore: Release version 1.1.0
This release features some cleanup and under-the-hood changes, as well
as "ecosystem-features" that don't directly affect the way Kontemplate
itself functions.

* Resource-sets are now passed on to kubectl in individual
  invocations. This means that kubectl errors can be scoped to
  individual resource set files and issues such as #51 are less of a
  problem.
* A Dockerfile is provided and published at `tazjin:kontemplate` on
  Docker Hub. This image contains `kontemplate`, `kubectl` and `pass`
  and can be used - for example - as an image for a step in a CI
  system.
* Kontemplate is now available on Homebrew, check the README for
  installation instructions.

* If different resource sets don't contain `---` separators in YAML,
  `kubectl` calls will no longer fail. (#51)
* Autocompleted trailing slashes in shells are now filtered from
  include & exclude lists to enhance the CLI experience slightly.
