version: Use linker flag 
Embedding the version file is slightly annoying for packaging, because
the release tarball is not a git repository and so "go generate" would
fail. Instead a packager would have to manually create the version.txt
file.
With using a linker flag, the version string has a graceful fallback.

silence: Fix broken ntfy action 
A silence action was added even when "base-url" was not set. This action
would of course fail, since there was no valid URL scheme given.
The action button is now removed in that case.

Add ability to silence alerts with ntfy action 
For now only for the single alert mode.
This is implemented as an action button, that will send an API request
to ntfy-alertmanager itself instead of Alertmanager. Here ntfy-alertmanager
acts as a proxy and will then do the API request for actually creating
the silence in Alertmanager.
This is founded in a limitation of ntfy, that seemingly does not allow a
json body with more than one key.

cache: Take alert status (firing, resolved) into account 
Otherwise a resolved alert would not trigger a notification, since its
fingerprint - which is a generated hash from the labels - remains the
same.

single mode: Cache alert fingerprints 
If ntfy-alertmanager breaks alertmanager's grouping feature, it should
take care of caching alerts on its own.

Set ntfy priority depending on Prometheus labels 
It is possible to configure a priority for an arbitrary label.
Furthermore a priority/order of those arbitrary labels should be
defined. The Alertmanager payload is checked for these and the
priority will be selected from the highest valued label that has one
set in the configuration file.

template usage in the future.
