Use .UTC everywhere we use time.Unix (#7066)

leak out (e.g. in the alert json). While this is harmless,

tsdb: don't allow ingesting empty labelsets (#6891)
* tsdb: don't allow ingesting empty labelsets

When we ingest an empty labelset in the head, further blocks can not be
compacted, with the error:

```
level=error ts=2020-02-27T21:26:58.379Z caller=db.go:659 component=tsdb
msg="compaction failed" err="persist head block: write compaction:
add series: out-of-order series added with label set \"{}\" / prev:
\"{}\""
```

We should therefore reject those invalid empty labelsets upfront.

This can be reproduced with the following:

```
cat << END > prometheus.yml
scrape_configs:
  - job_name: 'prometheus'
    scrape_interval: 1s
    basic_auth:
      username: test
      password: test
    metric_relabel_configs:
    - regex: ".*"
      action: labeldrop

    static_configs:
    - targets:
      - 127.0.1.1:9090
END
./prometheus --storage.tsdb.min-block-duration=1m
```
And wait a few minutes.

Julius Volz ae93bae88f Fix: exclude metric name in labels.MatchLabels() (#6523)
This function is only used in one place to format an error message when
encountering multiple matches on the "one" side of a
one-to-many/many-to-one vector match, which is probably why nobodoy has
noticed this before. The hashing is already done correctly and excludes
the metric name label when using the "ignoring" matching modifier.
