Fix 5.15 CI errors

[vga91]

• added @Context URLAccessChecker urlAccessChecker where needed

Fixes due to this Core breaking-change:

• changed http://bit.ly with https://bit.ly,
  otherwise the checkUrl throws a java.io.FileNotFoundException: http://67.199.248.10/2nXgHA2

• added LoadS3Test.removeRegionFromUrl(url),
  since the URL with the region,
  e.g. s3://us-east-1.127.0.0.1:60082/test-bucket/test.csv?accessKey=accesskey&secretKey=secretkey,
  throws an java.net.UnknownHostException: us-east-1.127.0.0.1: nodename nor servname provided, or not known,
  and we cannot change the s3Container.putFile(<FileName>); method since is in Core
