explicit outgoing addresses to make PCAPs easier to read

See merge request !205

Since migration to network namespaces PCAPs are harder to read because
source and destination addresses are always the same. This is AFAIK
caused by kernel routing and works as intended for real networks.

In our case all IP addresses are on local interfaces so we can
explicitly configure outgoing addresses in daemons and this will
again produce PCAPs where source address matches address assigned to
the daemon by Deckard.

At the moment Deckard assigns only one IPv4 or IPv6 address to binary
under test, i.e. this is not a complete fix: In cases where daemon has
IPv4 address assigned by Deckard but decides to contact IPv6 server it
will use the same address as source and destination.

deckard: make conncheck optional

See merge request !196

Make connection check on daemon startup optional. It is useful for
testing combinations of binaries where some of them are only clients
or communicate with others via non-DNS protocols (like cache garbage
collector).

rplint improvements

As far as I can tell self.fields was not used outside of this function
so I removed it.

allow verbose logging under xdist

See merge request !193

It is not clear why 8e9f5639 disallowed
verbose logging under xdist. It seems to work with:
- python 3.8.5
- py.test 6.0.1
- xdist 1.34.0

Monotonic time tests

this is done by appending `-monotonic` to the .rpl filename
