Set up DSCP prioritization through the iproute2 dcb tool, which is easier
to understand and manage.

When DSCP is updated through an offloaded pedit action, DSCP rewrite on
egress should be disabled. Add a test that check that it is so.

Commit dedfde2fe1c4 ("mlxsw: spectrum_dcb: Configure DSCP map as the last
rule is removed") fixed a problem in mlxsw where last DSCP rule to be
removed remained in effect when DSCP rewrite was applied.
Add a selftest that covers this problem.

These two tests have some problems in the global scope pollution and on
contrary, contain unnecessary local declarations. Fix them.

The current ping intervals are too short for running mirroring tests in
simulator. This leads to ping sending a follow-up ping before the reply
arrives, thus sending more than the requested 10 ICMP requests. This
traffic is seen at the counters, and causes spurious failures.
Bump interval and timeout numbers 5x in mirroring tests to address the
spurious failures.

The current timeout (2 seconds) proved to be too low for some (emulated)
systems where we run the tests.
Make the timeout configurable and default to 5 seconds.

Verify that with that sysctl turned off, DSCP prioritization and rewrite
works the same way as in qos_dscp_bridge test. However when the sysctl
is charged, there should be a reprioritization after routing stage,
which will be observed by a different DSCP rewrite on egress.
