Document-merge-service

Fix
* Allow isolation of unoconv calls to be disabled (default) ([`74834f1`](https://github.com/adfinis-sygroup/document-merge-service/commit/74834f1c820eb258e53697ecd563f1ee353a5e66))

Important: Be aware that the docker-container needs CAP_SYS_ADMIN since version 4.7.0

Fix
* Log an error if unoconv or unshare fails ([`6e2f54a`](https://github.com/adfinis-sygroup/document-merge-service/commit/6e2f54ad961cdfb0052c0a03823121ccf53b68ae))

Breaking
* Drop support for Python v3.7. This should have been done in 29a49ee76b638f0a8fb7b189fb91e61c45d78bde which updated the python version to 3.10 which is too restrictive. We now guarantee support for python versions 3.7 to 3.10. ([`920c0bd`](https://github.com/adfinis/document-merge-service/commit/920c0bd2c5c0dfe836b5b215a91691a4077fd63b))
