* Chore: explore possibilities of using makefile
This is an exploratory commit - I wanted to see how
revive/gosec linters could be integrated with makefile and our build scripts.
Looks better then I expected :)
* Chore: make revive happy
Revive execution was not supplied with path, if you restore there is couple
errors that were popping up - so I fixed them
* Chore: make revive happy
Since we do not like some of the default golint rules,
this commit proposes to use https://github.com/mgechev/revive.
And potential revive speed-up should't hurt :).
Right now, presented config (./conf/revive.toml) is permissive,
we might improve it over time however. Fixes for found revive
issues in the code are very limited so it wouldn't be large to review.
Also in this commit:
* Add annotations for makefile commands and declare phony targets
* Rename "gometalinter" script and CI command to "lint"
since we are doing there a bit more then using gometalinter package
* Add Makefile rules to .editorconfig
* Documentation which mentioned "golint" replaced with revive
Fixes#16109
Ref #16160

* Add new build info metrics that contains more info
The goal was to add more information about Grafana. But rather than
just adding those to the current metrics I created a new metric
since its a common pattern in the prometheus community to expose that
info in a metric named `*_build_info`.
We keep the old metric to avoid introducing any breaking changes but
we should be able to remove it the next breaking change

* Reopen log files after receiving a SIGHUP signal
Implements a system signals listener in log.FileLogWriter.
After receiving a SIGHUP signal from the system, the listener will close the current log file and then open it again.
The listener will finishes after receiving a SIGINT, SIGKILL or SIGTERM signal.
Closesgrafana/grafana#2497
* Move the SIGHUP handling to the main file
