deleting request

[ivukotic]

as a user, I want a trashcan icon in the request table.
This should delete all the traces of the request and data from s3 too.

Can this be implemented as a special case of the cleanup script?

[ivukotic]

it could if we would introduce another request state "Marked for deletion". It also requires a bit of web frontend development.
