lib/promscrape: do not re-use previously loaded scrape targets on failed attempt to load updated scrape targets at file_sd_configs
...
The logic employed for re-using the previously loaded scrape target was broken initially.

lib/promscrape: implement target-level and metric-level relabel debugging

Target-level debugging is performed by clicking the 'debug' link at the corresponding target
on either http://vmagent:8429/targets page or on http://vmagent:8428/service-discovery page.
Metric-level debugging is perfromed at http://vmagent:8429/metric-relabel-debug page.

lib/promscrape: optimize service discovery speed
...
- Return meta-labels for the discovered targets via promutils.Labels
instead of map[string]string. This improves the speed of generating
meta-labels for discovered targets by up to 5x.
- Remove memory allocations in hot paths during ScrapeWork generation.
The ScrapeWork contains scrape settings for a single discovered target.
This improves the service discovery speed by up to 2x.

lib/promscrape: allow specifying full target url in __address__ label
...
Previously the `__address__` label could contain only `host:port` part of the target url,
while the scheme and metrics path were obtained from `__scheme__` and `__metrics_path__`
labels. Now it is possible to set the full url in `__address__` label.
This makes valid the following scrape config, which is frequently used by novice users:
scrape_configs:
- job_name: foo
static_configs:
- targets:
- http://host1/metrics1
- https://host2/metrics2

lib/promscrape: properly implement ScrapeConfig.clone()

Previously ScrapeConfig.clone() was improperly copying promauth.Secret fields -
their contents was replaced with `<secret>` value.
This led to inability to use passwords and secrets in `-promscrape.config` file.

Reduce the number of memory allocations in this function. This improves its performance by up to 50%.
This should improve service discovery speed when big number of potential targets with big number of meta-labels
are generated by service discovery.
