This commit adds ability to select series matching distinct filters via a single series selector.
For example, the following selector selects series with either {env="prod",job="a"}
or {env="dev",job="b"} labels:
{env="prod",job="a" or env="dev",job="b"}
The `or` filter is supported in all the VictoriaMetrics tools now.
