netavark IPAM assignment

Add a new boltdb to handle IPAM assignment.

The db structure is the following:
Each network has their own bucket with the network name as bucket key.
Inside the network bucket there is an ID bucket which maps the container ID (key)
to a json array of ip addresses (value).
The network bucket also has a bucket for each subnet, the subnet is used as key.
Inside the subnet bucket an ip is used as key and the container ID as value.

The db should be stored on a tmpfs to ensure we always have a clean
state after a reboot.
