This refactoring brings in device Cache running in its own
thread and scanning FPGA devices once every 5 secs. Then no timers
are used inside ListAndWatch() method of device managers and
no need to run scanning periodically in every device manager's
thread.
Cache generates update events and the plugin creates, updates or
deletes device managers on the fly upon receiving the events.
Introducing new modes of operations is a matter of adding a single
function converting and filtering the content of Cache.

gofmt 33%
Gofmt formats Go programs. We run gofmt -s on your code, where -s is for the "simplify" command

Added mode ("af" or "region") prefix to the resource name to
distingush between announced functions and regions, e.g.
intel.com/fpga-af-f7df405cbd7acf7222f144b0b93acd18
intel.com/fpga-region-ce48969398f05f33946d560708be108a
By default the fpga plugin announce regions' interface IDs. With
added `-mode af` switch the plugins announces IDs of accelerator
functions instead of regions.
