Perform one retry on any discovery failure

The discovery phase of mapper is very CPU intensive on the BMC.
Situations have arisen, especially on BMC resets with the host
up, where a timeout occurs when mapper is discovering an object
on the dbus. The effects of mapper not discovering an object
can have large impacts to the system.

Testing: Validated in QEMU that the retry path was hit and the
retry successfully discovered the object. Verified on a witherspoon
that the retry path was hit and was successful.
