Old implementation has used process id instead, but it leads to log

* add --server flag for setup command
* restore behavior of the httploghandler
This feature sometimes causes the main process termination. Since the
child process has been already terminated (or going to) there is no need
to terminate it manually
In previous revisions server was terminated by itself, thus no lock or
socket was removed. In new version, graceful termination of the queue
has been added as well as server now handles singals
Some commands have been moved to another group and thus having another
default name (old subcommands are still available...for now):
* daemon -> repo-daemon
* key-import -> service-key-import
* repo-clean -> service-clean
* repo-config -> service-config
* repo-config-validate -> service-config-validate
* repo-setup -> service-setup
* repo-shell -> service-shell
* version -> help-version
* add external process spawner and update test cases
* pass no_report to handlers
* provide service api endpoints
* do not spawn process for single architecture run
* pass no report to handlers
* make _call method of handlers public and also simplify process spawn
* move update under add
* implement actions from web page
* clear logging & improve l&f
