Revert "Attempt to support both OCM 1.0 and 1.1 when accessing remote…

… shares"

This cannot work, by construction we can't use basic and bearer auth.
We could instead store the share type and decide accordingly,
but for now Reva only remains capable to connect to OCM 1.1 systems.

This reverts commit e6ab385.
