No meaningful changes otherwise. :)

Accidentally referenced arm instead of arm64

Done to show non-root usage and more inbuilt utilities

Fixing this by switching to tox outside the venv

Also adding more python versions

Now deploy both to pypi and docker hub after all tests pass

    Default  ERROR
    -v       WARNING
    -vv      INFO
    -vvv     DEBUG

* Correct env variable name in minitor_test
* Adding more test environments, skipping python 3.5
because lack of assert_called_once support
* Using default travis python environments

These are bundled within the Docker image to make it possible to alert
on status of other Docker containers.

Will potentially include other sets of "standard" scripts for
convenience sake.

It looks like yamlenv doesn't parse quite correctly and seems to think
the `:` removed in this diff is defining a new object.

I believe it has something to do with a change in yamlenv 0.6.0 to allow
interpolating env variables as yaml literals.

Metrics got broken when counters were moved to be initialized below the monitor creation

Doubles as a health check endpoint!

Change some methods to private and rearrange them

This is why I need integration tests...

Update readme to document the new templating vars

This will allow `latest` to be `master` and allow git tags to dictate
tagged versions on Docker.

Also update readme to describe how it's now building

Based on the idea from SeaLife, adds alerts for when a monitor comes out
of an alerting down state. Also includes a bunch of unit tests to cover
the new code.
