9f578e389c vmalert: add function "query", "first" and "value" to alert templates functions (#960) 
The commit adds a support for template function `query`,
`first` and `value`. The function `query` executes
a MetricsQL query for active alerts. In vmalert we
update templates on every evaluation for active alerts
to keep them up to date. With `query` func it may become
a perf issue since it will fire a query on every execution.
We should keep it in mind for now.

dafef21001 all: use go install instead of go get for installing auxiliary tools 
This is a preparation for Go 1.16, which deprecates `go get` for installing binaries.
See https://tip.golang.org/doc/go1.16#go-command :

  go install, with or without a version suffix (as described above), is now the recommended way
  to build and install packages in module mode. go get should be used with the -d flag to adjust
  the current module's dependencies without building packages, and use of go get to build and install
  packages is deprecated. In a future release, the -d flag will always be enabled.

38188e1d6b lib/promscrape: store ScrapeWork items by pointer in the slice returned from get*ScrapeWork() 
This should prevent from possible 'memory leaks' when a pointer to ScrapeWork item stored in the slice
could prevent from releasing memory occupied by all the ScrapeWork items stored in the slice when they
are no longer used.
