rules: Allow recorded rules expressions to be scalars.

This is useful if you want to build up a constant metric,
such as a set of alert thresholds that vary by label value.

Remove multi-statement queries
...
This commit removes the possibility to have multi-statement queries
which had no full support anyway. This makes the caller responsible
for multi-statement semantics.
Multiple tests are no longer timing-dependent.

Deprecate `keeping_extra`, rename it to `keep_common`.
...
`keep_common` is more in line with the function name
`drop_common_labels()` terminology-wise, and also more in line with
`group_left`/`group_right` (no `...ing` verb suffix).
We could also go the full way and call it `keep_common_labels`. That
would have the benefit of being even more consistent with the function
`drop_common_labels()` and would be more explanatory, but it also seems
quite long.
