In the reported bug, a regression was introduced in [1] when limiting
the time to have a "dnsmasq" process enabled. It has been reported, as
documented in the bug, that in older versions (Queens), using Python 2
[2] and older versions of "ip_lib" (not implementing most of the
commands using Pyroute2), that the time needed to spawn a "dnsmasq"
process exceeds the default 60 seconds defined in
"common_utils.wait_until_true".
This patch increases this time by a reasonable 300 seconds.
