Public bug reported:

When a new port gets added or removed, the DHCP agent is currently
dumping the entirety of the hosts file in the logs. This is a problem in
some deployments we have encountered, some of which with upwards of
10000 ports.

Change-Id: I3ad7864eeb2f959549ed356a1e34fa18804395cc removed logging
calls from inside the loop. It also added two new log calls: one at the
beginning of the loop that builds the hosts file in memory and one at
the end, that also includes the full content. Those could be useful
pieces of debugging information. However, adding the host file contents
can get expensive when there are large numbers of ports.

Will propose a patch to keep the log message, but remove the file
contents.
