Add a configurable sleep before IPA starts working
Some kernel modules take substantial time to initialize. For example,
with mpt2sas RAID driver inspection and deployment randomly fail
due to IPA starting before the driver finishes initialization.
As much as I hate it, the only way to guarantee that the hardware is
truely initalized is to wait for it. Apparently all hardware in Linux
is treated as hotplugged, so there is no such thing as "hardware
initialization is finished". Operators can add a sleep based on their
knowledge of their hardware.
The default behaviour remains the same.
