f5cb213ef9 lib/storage: reuse timestamp blocks for adjancent metric blocks with identical timestamps
This should reduce disk space usage when scraping targets containing metrics with identical names
such as `node_cpu_seconds_total`, histograms, quantiles, etc.

Expose `vm_timestamps_blocks_merged_total` and `vm_timestamps_bytes_saved_total` metrics for monitoring
the effectiveness of timestamp blocks merging.

fb356c434b Changed s3 configProfile flag default, (#749)
aws sdk has complicated logic for chosing profile name and we shouldn't set
it to `default` value. It leads to bugs and improper configuration.
Set it to empty value by default is safe. It will be automatically set to `default` by sdk.

478d8f8393 app/vmselect/promql: add count_le_over_time(m[d], le) and count_gt_over_time(m[d], gt) functions
These functions returns the number of raw samples that don't exceed `le` or are bigger than `gt`.
These functions are complement to already existing `share_le_over_time(m[d], le)` and `share_gt_over_time(m[d], gt)`.

80a9dc79fe changed vmalert behaviour (#738)
* VMAlert start with empty rules dir

There are some applications (operator for instance), that generates alerts configuration at runtime
and vmalert must start correctly without rules to support this behaviour.
Later application will add rules files and send SIGHUP to vmalert,
which will trigger reading rules files and start rules exectuion.

Removing rules files with SIGHUP signal must stop rules execution and
vmalert will wait for new rules.

* imports sorted

* added test cases for empty rules, removed blank line

* fixed imports conflict

* updated tests

because `sw.labels` may be reset multiple times when processing big number of rows.

432c0383db Single dashboards update (#736)
* dashboard: rename var `datasource` to `ds` for consistency reason

Dasbhoards for cluster version or vmagent operate with datasource variable
named `ds`. For consistency sake we rename this variable in single node version
as well.

* dashboard: add instance variable picker

See dashboard reviews here https://grafana.com/grafana/dashboards/10229/reviews

* dashboard: limit number of buckets in histogram to 12 for vmagent dashboard

* dashboard: bump version requirement in description for single version

* dashboard: drop extra series override for single version

* dashboard: set Y-min to zero for most of panels in vmagent dashboard
