[route_maps] Enable handling of route-maps without set/match (#856)

* Enable handling of route-maps without set/match

This commit introduces the ability to handle simple route-maps
that do not contain set or match statements.

Specifically, it allows for the creation and management of
purely basic route-map entries like 'route-map test-1 permit 10'.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Add changelogs

* Fix ansible-lint error
