lib/promrelabel: fix parsing regex: true

lib/promrelabel: add keep_metrics
and drop_metrics
actions to relabeling rules
...
These actions simlify metrics filtering. For example,
- action: keep_metrics
regex: 'foo|bar|baz'
would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted.
The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above:
- action: keep_metrics
regex:
- foo
- bar
- baz

* new feature: relabel logging
Use scrape_configs[x].relabel_debug = true to log metric names inkl.
labels before and after relabeling. After relabeling related metrics
get dropped, i.e. not submitted to servers.
* vminsert wants relabel logging, too.

and drop_if_equal
actions to relabel configs
...
These actions may be useful for filtering out unneeded targets and/or metrics if they contain equal label values.
For example, the following rule would leave the target only if __meta_kubernetes_annotation_prometheus_io_port
equals __meta_kubernetes_pod_container_port_number:
- action: keep_if_equal
source_labels: [__meta_kubernetes_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]
