Add 'scan' verb for runtime device scan

Changes:
- Add 'scan' verb so client can pass 'filter'(udev rules in JSON
format) and 'mask' (desired data fields mask) arguments.
'filter' & 'mask' can include 'properties' and 'attributes' sub-
fields so their key & values act as parameters for device scanning
and mask the scanned devices properties & attributes when service
report back. The 'filter' argument can contain an additional field
with 'tags' key and JSON array value hence the tags will match for
device scanning too.
