revise /api/v1/series docs (#746)
* revise /api/v1/series docs

Further clarification for #735

  * clarify how default range differers from Prometheus API
  * avoid `start=0` suggestion when confirming delete, because it will cause a timeout in most deployments

* Update README.md

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.

e1c2757f70 vendor: update github.com/VictoriaMetrics/metricsql from v0.4.3 to v0.5.1
The new version of the package supports binary operations on string literals:

    * "foo" == "bar"    => NaN
    * "foo" == "foo"    => 1
    * "foo" >bool "bar" => 1
    * "foo" < "bar"     => NaN

f4e7e5fb90 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)`.

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

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

vmalert: update -rule flag description to enforce quotes using (#709)
Description for `-rule` flag uses as example specific chars like asterisks
which could be interpreted wrong by different shells. To avoid this, description
now contains quoted flag values.

lib/flagutil: avoid int overflow for arch 386 (#710)
Arch 386 is a 32-bit architecture and interprets int type for numbers as an explicit int32,
whereas on most modern CPUs int is implicitly an int64. This makes tests to fail with
`int overflow` error.

efc730863b lib/promscrape: reduce memory usage when scraping targets with big number of metrics alongside targets with small number of labels
Previously targets with big number of metrics and/or labels could generated too big buffers,
which then could be re-used when scraping targets with small number of metrics.
This resulted in memory waste.

Now big buffers are used only for targets with big number of metrics / labels,
while small buffers are used for targets with small number of metrics / labels.
