We have plenty of paths used in the application, but two of them
are hardcoded in examples all over the code for historical reasons.
I found that by default in Docker, the path would resolve to the value
we are setting it explicitly to, so it doesn't make sense to set
a few variables we are setting now explicitly.
* support flags commands, move to cmd
* fix target name
* test for happy path importer
* add export cmd
* fix wrong import, lint warns
* increase test timeout
* add sellp to allow main test server to start
* implement all cmds
* handle backup/restore errors
* fix import status check, hide secret from logs
* backup cmd err tests
* randimize test port
* avoid dup code in Last controller
* add target to make all bin archives
* remove container in make
* add smiple scripts to simplify commands, update readme
* add docs on dockerless, enforce app user
* add restore info
* move last to lastCommentsScope const
