Release v5.0.7

v5.0.7 Release notes

Bug Fixes:

1. Re-introduce missing samples/validate endpoint
   In last release we have removed samples/validate endpoint in favour of validate endpoint.
   But since most users are using samples/validate we will keep this and deprecate in a future release.

2. Support both json and hal+json for accept header
   Validate endpoint did not support hal+json accept header in last release. We will include support for this.

3. Enable ENA to pre-accession samples using WEBIN authentication instead of AAP
   ENA will pre-accession samples using a WEBIN super user (prefixed SU-) and the metadata submission will be done by a non super user.
   During metadata submission we will check if the sample has been accessioned by the ENA registered super user and
   if yes then we will allow submission by any general webin user who wants to submit metadata against the accession.
