Add a test case where 'named' is restarted and ensure that an already
signed zone does not change its NSEC3 parameters.
The test case first tests the current zone and saves the used salt
value. Then after restart it checks if the salt (and other parameters)
are the same as before the restart.
This test case changes 'set_nsec3param'. This will now reset the salt
value, and when checking for NSEC3PARAM we will store the salt and
use it when testing the NXDOMAIN response. This does mean that for
every test case we now have to call 'set_nsec3param' explicitly (and
can not omit it because it is the same as the previous zone).
Finally, slightly changed some echo output to make debugging friendlier.

Add a script similar to conf.sh to include common functions and
variables for testing KASP. Currently used in kasp, keymgr2kasp, and
nsec3.
(cherry picked from commit ecb073bdd6)
GitLab issue #2498 is a bug report on NSEC3 with dynamic zones. Tests
for it in the nsec3 system test directory were missing.
(cherry picked from commit 0c0f10b53f)
Upon request from Mark, change the configuration of salt to salt
length.
Introduce a new function 'dns_zone_checknsec3aram' that can be used
upon reconfiguration to check if the existing NSEC3 parameters are
in sync with the configuration. If a salt is used that matches the
configured salt length, don't change the NSEC3 parameters.
(cherry picked from commit 6f97bb6b1f)
Implement support for NSEC3 in dnssec-policy. Store the configuration
in kasp objects. When configuring a zone, call 'dns_zone_setnsec3param'
to queue an nsec3param event. This will ensure that any previous
chains will be removed and a chain according to the dnssec-policy is
created.
Add tests for dnssec-policy zones that uses the new 'nsec3param'
option, as well as changing to new values, changing to NSEC, and
changing from NSEC.
