vmalert: skip automatically added labels on alerts restore (#871) 
Label `alertgroup` was introduced in #611 and automatically added to generated
time series. By mistake, this new label wasn't correctly purged on restore event
and affected alert's ID uniqueness. This commit removes `alertgroup` label
in restore function.

45f7cdc532 Revert "app/vmselect/promql: remove metric name after applying ceil, floor and round functions in order to be more consistent with Prometheus" 
This reverts commit ac45082216.

Reason for revert: the previous behavior for VictoriaMetrics is easier to understand and use by users -
functions, which don't change the meaning of the time series shouldn't drop metric name.

Now the following functions do not drop metric names:

* ceil
* floor
* round
