ONHOLD/WIP: POC allow customizing supported formats via app config

[mrow4a]

feat: #207
feat: https://github.com/owncloud/enterprise/issues/3061

previous: it was not possible to specify which formats are supported by Collabora
now: it is possible to specify formats with which Collabora should be opened

todo:

• settings for formats are populated from backend
• app setting can be added command line
• probably needs also mapping from extension to format e.g. ("application/pdf"->".pdf") (1md)
• app setting can be added in Admin UI (this parts begs for refactor but can be like this too..) (1-2md)
• validate settings added whether they are really supported by collabora (0.5md)
• add tests and qa (2md)
• add admin docs (0.5md)

By default all supported formats are allowed, to customize execute (e.g. remove pdf if not needed):

occ config:app:set richdocuments supported_mimetypes --value '["application\/pdf","application\/vnd.oasis.opendocument.text","application\/vnd.oasis.opendocument.spreadsheet","application\/vnd.oasis.opendocument.graphics","application\/vnd.oasis.opendocument.presentation","application\/vnd.oasis.opendocument.text-flat-xml","application\/vnd.oasis.opendocument.spreadsheet-flat-xml","application\/vnd.oasis.opendocument.graphics-flat-xml","application\/vnd.oasis.opendocument.presentation-flat-xml","application\/vnd.lotus-wordpro","image\/svg+xml","application\/vnd.visio","application\/vnd.wordperfect","application\/msonenote","application\/msword","application\/rtf","text\/rtf","text\/plain","application\/vnd.openxmlformats-officedocument.wordprocessingml.document","application\/vnd.openxmlformats-officedocument.wordprocessingml.template","application\/vnd.ms-word.document.macroEnabled.12","application\/vnd.ms-word.template.macroEnabled.12","application\/vnd.ms-excel","application\/vnd.openxmlformats-officedocument.spreadsheetml.sheet","application\/vnd.openxmlformats-officedocument.spreadsheetml.template","application\/vnd.ms-excel.sheet.macroEnabled.12","application\/vnd.ms-excel.template.macroEnabled.12","application\/vnd.ms-excel.addin.macroEnabled.12","application\/vnd.ms-excel.sheet.binary.macroEnabled.12","application\/vnd.ms-powerpoint","application\/vnd.openxmlformats-officedocument.presentationml.presentation","application\/vnd.openxmlformats-officedocument.presentationml.template","application\/vnd.openxmlformats-officedocument.presentationml.slideshow","application\/vnd.ms-powerpoint.addin.macroEnabled.12","application\/vnd.ms-powerpoint.presentation.macroEnabled.12","application\/vnd.ms-powerpoint.template.macroEnabled.12","application\/vnd.ms-powerpoint.slideshow.macroEnabled.12"]'
