`_blob` endpoint redirects in CrateDB loose Basic HTTP Auth headers

[matriv]

With: crate/crate@c8a0dcc fix for _blobs authorization, it's required for blob actions to make sure that Basic HTTP Auth headers are set, even if CrateDB redirects the http request to a different node (the one that holds the shard of the blob table, for performance purposes. By default http clients drop the Basic HTTP Auth headers in the case of a redirect (for security reasons). Please check the relevant issue: crate/crate#19335
