Key changes: * Added `mle_router_role_allowed` nexus test, which includes a test of the correct type of advertisement used by each type of node. * Updated the `router_downgrade_on_sec_policy_change` nexus test to also test changes of the Router role allowed/disallowed when multiple factors are changed * Updated checks in `verify_1_1_5_3_6.py` to verify that only Router advertisments are sent during the test, to verify that REED advertisements are not sent unless the unit is no longer attempting to upgrade

# Test differing behaviors based on the Router role allowed

#
|
|
# Purpose & Description
|
|
# This test validates that correctly-formatted transmissions occur based on whether the Router
|
|
# role is allowed. This includes Advertisements (only from REEDs and Active Routers),
|
|
# which should not occur for devices with Router role disallowed.
|
|
# This test verifies Router role disallowed on FED and MED devices, with a duplicate
|
|
# pair used to demonstrate that these transmissions begin in the correct format when
|
|
# re-configured so that the Router role becomes allowed.
