* stop using XDG_CACHE_HOME as home directory
XDG_CACHE_HOME is not a substitute for $HOME, see [1].
[1]: https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html
* fix bats testing setup/teardown
since cmdutil.Homedir() would treat $XDG_CACHE_HOME as $HOME, deleting
$XDG_CACHE_HOME would wipe out previous kubens state. now that we're not
doing that, we need to make a real synthetic $HOME and clear it out so
that $HOME/.kube/kubens doesn't persist between runs.
* add unset flag
* test unsetting selected context
* update readme with new unset flag
* testdata notes
* set a current context
* cleanup
* omit fixture changes
- add .travis.yml.
- move bats fixtures to .bats extension, since it allows detection of test
files automatically by file extension.
- use BATS_TEST_DIRNAME variable to compute location of COMMAND.
- IMPORTANT: use `echo "$output">&2` before final check so that we can debug
the test cases by their output
