consolidate configuration options into a single resource
Currently plugin configuration is spread across different places and makes use of different techniques:
Current status:
- most of the plugin configuration options are topics editable for members of the "Administration" workspace through the dm4-webclient (see migration1)
- In the plugin.properties there is a configuration option to build the plugin in either french, english or german language
- currently there are two methods in the sign-up plugin implemented to send mails (dm4-sendgrid, dm4-mail) but no configuration option to switch between these two (the switch is hard-coded)
