Document-merge-service

Fix
* **validation:** Fix excel template validation ([`3c6149e`](https://github.com/adfinis-sygroup/document-merge-service/commit/3c6149e15a455539f544c61084a0e372cc74fa7b))

Fix
* Allow isolation of unoconv calls to be disabled (default) ([`74834f1`](https://github.com/adfinis-sygroup/document-merge-service/commit/74834f1c820eb258e53697ecd563f1ee353a5e66))
* Remove security restrictions to make unshare possible ([`5b10cff`](https://github.com/adfinis-sygroup/document-merge-service/commit/5b10cffac5bd365d02c16999748113747d6d36e9))

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))

Fix
* Move temporary path to data directory
([`afce2ca`](https://github.com/adfinis-sygroup/document-merge-service/commit/afce2ca3429bf20d6c282fe5f8a1f1201fc278ee))

Fix
* **docker:** Fix docker uwsgi command ([`85892f6`](https://github.com/adfinis/document-merge-service/commit/85892f63005fe31b277ba8df623c8a0ec0f1b7ec))

Feature
* **license:** Switch license from MIT to GPL-3.0-or-later ([`47c1a84`](https://github.com/adfinis/document-merge-service/commit/47c1a843a9cda105d1640651a8231fbc4c18039f))

Fix
* **python:** Use python v3.8 ([`920c0bd`](https://github.com/adfinis/document-merge-service/commit/920c0bd2c5c0dfe836b5b215a91691a4077fd63b))

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))
* document-merge-service is now released under the GPL-3.0-or-later license. ([`47c1a84`](https://github.com/adfinis/document-merge-service/commit/47c1a843a9cda105d1640651a8231fbc4c18039f))
