[EPIC] Activate TER release by git tagging

Requirements for extension owner

• The extension owner must have added a link to the public repository in the TER settings for the extension
• The extension owner must have added a web hook to the repository (GitHub, GitLab, Bitbucket, etc.)
• The extension must contain a valid composer.json
• The extension must require TYPO3 in the composer.json
• The composer.json must contain a title, a description and the extension key

No ext_emconf.php anymore?

What important information is included in ext_emconf.php currently?

• title => title in composer.json
• description => description in composer.json
• author, author_company and author_email => authors section in composer.json
• version => Git tag
• category => Needed? Can be provided by description or keywords. Often an extension touches many categories.
• state => Needed?
• uploadfolder => Needed?
• clearCacheOnLoad => Should always be true, shouldn't it?
• constraints => can be handled by the require section in composer.json

The check for a new release

1. TER gets information about new release by the web hook
2. TER fetches the information and creates records (for search and for populating data of e.g. documentation)
3. TER updates extensions.xml file

Installation in TYPO3 has no ext_emconf.php

• When downloaded, the Extension Repository will add an ext_emconf.php generated by the information provided by composer.json
