Make block devices without partition/partitiontable visible in model

See merge request mer-core/nemo-qml-plugin-systemsettings!91

This can be used e.g. when showing unsupported partitions.

This commit adds signleton block devices container that is the main
interface that monitor uses for operating block devices. The block devices
emits a signal (newBlock) when it sees an acceptable new block device and throws
away the ones that cannot / should not be shown in the model.

When block device container sees a block device that could be a container
for a partition, it'll wait for 3000ms milliseconds before accepting the
block. If partition appears during this inverval, then waiting is cancel.
