Alertmanager templates testing

Render Alertmanager templates locally

Normally to test Alertmanager templates you need to restart running Alertmanager and wait for alerts to arrive to Slack or email. To speed up this process parts of templates could be rendered locally using predefined alerts data without the need of the actual Alertmanager.

What you still need in this case is amtool which is a part of Alertmanager delivery which could be downloaded here https://github.com/prometheus/alertmanager/releases

Some examples of templates rendering:

## Why become an SPI Associated Project?
Gentoo, as a collective of software developers, is pretty good at being a Linux
distribution. However, the legal & organization overhead required to convert
the existing corporation into a successful non-profit recognized at the federal
level in the USA would be a significant increase in non-development workload.
The historical baggage of the Gentoo Foundation, with bylaws restricted
behavior to that of a non-profit, and as a non-profit recognized only in the
state of New Mexico, but considered as a for-profit entity at the US federal
