Use Console as proxy for share object logic

[cesnietor]

closes: #3255

Share File URL now points to Console to facilitate sharing the url in case MinIO endpoint is not exposed.

Changes:

• Update how we return the share url pointing now to Object Browser API instead of MinIO endpoint
• Adds new endpoint to validate share link url (base64encoded) and download file
• unittests to validate url

How it looks:

When url expired:

Test steps:

With an existing bucket, folder and objects.

• Click share file
• Copy and paste the new url in the browser
• The url should contain same url as Object browser
• Object should be downloaded
• Test injecting wrong urls (base64encoded)
• Should return error or forbidden errors if url doesn't point to internal MinIO server

LGTM, Tested in local env as well as making a custom MinIO build with this fix.

@cesnietor , Do we still need to limit the number of hours as in the screenshot?

Also the subpath based console ui seems to show the minio server url . is this fine?

@prakashsvmx yes we still need to do the hour limitation since the url is signed with that expiration.

based console ui seems to show the minio server url

@prakashsvmx it's fine if the new url is using the subpath. Or do you mean the encoded minIO url is using the subpath? could you please give me an example? or what do you mean?
