dynamodb election:
- find node responsible for key K
- look up K 'master'
- value in K is of the format <seqid>|<status>|<address>|<port>
- if addr:port is self and status != C, then assume role, incr seqid and poll/update K every N/2
- connect to addr:port
- if connected, it would only respond with results if it is still within timer,
  else it would send back notification of not-responsible-any-more.
- if not responsible, check store again
- else, initiate new election
   - CAS with status set to "C" (Contested)
   - wait N seconds
     - if node exists, it would have updated status back to OK
   - CAS with new address and port
- if leader, check K every N/2 and set status to OK
