multi-tenancy

answer 405 to unsupported methods on the discovery endpoints

strict type checking

- Requires scim2-models 0.10.0.

- A PUT that changes nothing keeps meta.lastModified and the ETag.
- Bulk requests are validated by scim2-models. An invalid operation fails alone.
- A bulk operation on an unknown endpoint returns 400 invalidPath instead of 404.
- Values the client sends in "status", "response" or "location" of a bulk operation are ignored.

chore: bump to 0.3.0

- --default flag, false by default

- docker image

- Fix multi-value attributes patch

- dependency update

fix: an error happening when PUT-ing an extension field to an instance

where there was None

fix: compatibility with scim2-models 0.4+
