The `--userland-proxy` daemon flag makes it possible to rely on hairpin
NAT and additional iptables routes instead of userland proxy for port
publishing and inter-container communication.
Usage of the userland proxy remains the default as hairpin NAT is
unsupported by older kernels.

This fixes a few misuses of `deleteAllContainers()` cleanup
method in integration-cli suite by moving call to the
beginning of the method and guaranteeing their execution
(including panics) with `defer`s.
Also added some forgotten cleanup calls while I'm at it.

If DOCKER_CLIENTONLY is set for test-integration-cli, we don't set
the 'daemon' build tag. 'isRemoteDaemon' will help us skip such
tests without a need to move them to a separate file and accidentally
lose track of them.
Added `testRequires` function to skip tests based on predefined
conditions evaluated in runtime. This way we can easily extend test
requirements like:
testRequires(t, Networking, SameHostDaemon, Linux)
