Refactor and port CLI from Docopt to Clap (#2066) (#6356)

* Refactor and port CLI from Docopt to Clap (#2066)

* Add --can-restart and --force-direct to help

* Add flag support to subc & move import/export options to subcommand

* Reorder subcommand args (put positional args last in CLI help message)

-Operating Options:
-  --mode MODE                      Set the operating mode. MODE can be one of:

-                                   active - Parity continuously syncs the chain.
-                                   passive - Parity syncs initially, then sleeps and
-                                   wakes regularly to resync.
-                                   dark - Parity syncs only when the RPC is active.
-                                   offline - Parity doesn't sync. (default: {flag_mode}).

-                                   (default: {flag_no_download}).

-                                   (default: {flag_base_path}).
-  --db-path PATH                   Specify the database directory path
-                                   (default: {flag_db_path}).

-                                   synchronize a bare minimum of data and fetch necessary
-                                   data on-demand from the network. Much lower in storage,
-                                   potentially higher in bandwidth. Has no effect with
-                                   subcommands (default: {flag_light}).
-
-Convenience Options:
--c --config CONFIG                 Specify a configuration. CONFIG may be either a

-  --unsafe-expose                  All servers will listen on external interfaces and will
-                                   be remotely accessible. It's equivalent with setting
-                                   the following: --{{ws,jsonrpc,ui,ipfs,secret_store,stratum}}-interface=all --*-hosts=all
-                                   This option is UNSAFE and should be used with great care!
