Release v0.10.0

[sysadmind]

Cut a stable release before larger refactoring changes.

Can you add a make update-go-deps to this?

Although, it looks like lib/pq changes some string formatting:

$ make test
>> running all tests
GO111MODULE=on go test -race  ./...

FAIL: postgres_exporter_test.go:218: FunctionalSuite.TestParseFingerprint

postgres_exporter_test.go:254:
    c.Assert(f, Equals, cs.fingerprint)
... obtained string = "'localhost':'55432'"
... expected string = "localhost:55432"

I bumped the modules, but lib/pq v1.10.2 seems to break illumos builds. I'll roll this back to v1.10.1 for now and submit an issue upstream.

LGTM

@SuperQ You will need to merge and tag. I don't have permissions on this repo

I've added the tag for the release, it should pop out of CI in a bit.
