Skilletcli

1.9.6 is an interim release that cleans up a lot of code and adds support for pip/pypi distribution. This release does not include any major features or bugfixes.

**New features**
* Added additional cmdline flags for username/address/password
* Added _keystore_, a method of storing, or at least caching, API keys. See the README for usage.

This release packages the appengine/firestore based API into the core code. This includes skupload.py, which can take skillets from git to firestore, assuming the user has creds to do so.

Aside from that, it also has a number of small feature enhancements.

**New Features**
* --repotype and --repopath both updated to include API endpoint as an experimental option. See [README](README.md) for more information.
* --validate allows the enabling of validation of device SSL certificates. This only affects connections to Firewalls, not to any other https endpoints which have cert validation enforced.
* Added and improved some warnings

**New features**
* See all remote skillet branches with _--branch list_
* Many testing improvements. Test against real devices with _pytest_!
* More graceful handling of device type mismatches or errors.

**Bugfixes**
* API_KEY_LIFETIME was missing from the example config_variables.yaml file, causing some snippets that use this to fail to push.

**New features**
Added --debug flag for better...debugging.
Dramatically improved help output.
Improved errors and warnings.

**Bug fixes**
Fixed issue where m-* series Panorama systems were incorrectly typed

**added**
Added JSON parser for variables file. The JSON file follows an identical structure to YAML, so the two can be used interchangeably.

**fixed**
- Incorrect dictionary key for skillet retrieval
