Remove S3 handling

[dominikl]

This PR removes minio dependency (and therefore S3 handling, has been deprecated already), it is actually not used anywhere.

https://github.com/ome/ome-common-java/blob/master/location-server/start-location.sh can likely go as well.

From discussion yesterday at the OME Formats meeting, the current proposal is to deprecate these APIs in Bio-Formats 8.4.0 in preparation for their removal from the ome-common library in Bio-Formats 9. I'll try to get something opened before the end of the calendar year

S3 methods are deprecated now (#110) I'll resurrect this PR, remove draft and see what breaks downstream (hopefully nothing). @sbesson suggested this might also superseed #109 as jackson dep was probably added just because the S3.

Closing/reopening to trigger the CI workflow

[dominikl]

Thanks Seb. Sorry, didn't see that workflow wasn't triggered.

Thanks @dominikl. Comparing the changes against the content of the original PR which introduced this functionality, noting a few additional places that should be cleaned up:

• location-server
• pom.xml: the jackson-* dependencies
• StreamHandle: the internal Settings class
• Location:
  • the UrlType enum
  • the isURL, urlType and uri private fields
  • the internal code paths that depend on these enum and fields
  • a few unused imports
