Add wis2box-create-config.py to generate configuration files

[maaikelimper]

In order to simplify the wis2box-configuration, we could have a script that is run from the command-line and asks the users for a series of questions and then generates the configuration-files.

So in addition to 'wis2box-ctl.py' we would have 'wis2box-create-config.py'

'wis2box-ctl.py' could run a test to check if the configuration-files are missing and suggest the user to run 'wis2box-create-config.py' first.

• Script asks for country/center-id and create data-mappings.yml for all 3 plugins for synop and for bufr for temp
• Script to ask for wis2box-directory and create directory structure and create empty station_list.csv
• Script to create basic discovery-metadata.yml in metadata/discovery/
• Script to auto-generate unique default passwords

[maaikelimper]

@tomkralidis Can we provide default keywords for synop and temp discovery metadata ?

I've created PR #476 for this.

Here is how it works:

The user executes the new script 'wis2box-create-config.py' and answers a series of question on the command-line:

PS C:\Users\maaik\Documents\GitHub\wis2box> python wis2box-create-config.py
