handle disk failures during tablet copies

There are two components in a tablet copy: the copy client (that
receives data) and the copy session source (that sends data).

Coarse-grain handling of disk failures during tablet copies is done for
the tablet copy client as:
* Before starting a copy client, if no disks are available to place the
  tablet, simply return (instead of failing a CHECK).
* Before downloading each WALs or block, check that the tablet is in a
  healthy group.
And for the tablet copy session as:
* Before sending a block or log segment, check if the tablet has an
  error.

Upon returning an error, the tablet copy client will shutdown the
replica, leaving it in a failed state.

A test is added to ensure that both copy clients and that source
sessions with failed disks will return errors to the copying client.
