Migrate command line tool from commandline to Click

Migrating to https://github.com/pallets/click as Debian Buster does not include python3-commandlines.

Choosed python3-click which is very popular and seems a good tool from my point of view.

• commandline is not very maintained
• Migrate to Click
• Pipenv implementation to get some inspiration

Migration steps

• Dependencies updates: rm commandlines, add click: Update README.md links, setup.py, and Pipfiles
• Asyncio handling: click issue asyncio, click PR asyncio handling, checks-buildkite-plugin, abot, msbot
• blocks:
  • (default=0, show_default=True) show_default only available for the option.
  • blocks: IntRange (min 0, max 5.000 BMA limit)
• tx: #131 (closed): FloatRange (min 0.01 for Ğ1, Ğ1-test?)
• implement -h (only works on root, not for sub-cmd) and -v

Breaking changes

• two sub-commands not possible for the same no longer possible
  • Removal of long sub-commands certification, transaction, network, identities
• -h only works on the program name but no longer for sub-commands
• remove usage command which can now be found with --help
• Scrpyt parameters: -n, -r, -p to --nrp 4096,16,1
• blocks:
  • --nbr/-n option Debian 0.6.5, as an argument in 0.7 (and 0 as default value)
  • option name: --last —> --detailed/-d
• Position of global options before sub-cmd: --gtest, --peer, --auth-*
• #167 (closed): rename amount to balance
• amount/balance: pubkeys separation: : –> (space)
• Rename generate_auth_file to authfile
• Add smaller option for --auth-*: --scrypt, -af, --seed, --wif
