Internal packages are supported by Go 1.5+, any package in /internal/ dir is only importable from the same repo. This will cleanup main dir a bit and provide better namespace for unsee subpackages
Fixes#104
@status filter was added to the master branch to support new status key from Alertmanager >=0.6.1
status ended up being nested in Alertmanager (it was added to solve AM issue 609 and that was a long PR with lots of changes), current unsee implementation ended being slightly off with how Alertmanager is naming this, it should actually be @state rather than @status.
Alertmanager 0.6.1 can return multiple instances of the same alert either in a different block object or as a duplicated alert group, ensure that we deduplicate those
We already compute alert sha1, it's a unique string so it's a good match for secondary sort key, used when two alerts have the exact same
timestamp. This helps to ensure that we always have a stable sort order and don't flash the UI if we have a group with alerts created at the exact same time
