Upload autorename on client side
Removes the need for POST to collection which would hit against upload
limits.

The client tries to auto rename the file by adding a suffix "(2)".
It tries to use the file list on the client side to guess a
suitable name. In case a file still cannot be uploaded and creates a
conflict, which can happen when the file was concurrently uploaded, the
logic will continue increasing the suffix.
