* Add aggregate functionality to eos_vrf
* Add tests for eos_vrf aggregate option
* Remove test2 and test3 vrfs at the beginning of the eos_vrf tests
* Pull all vrfs
With aggregate, we need to get all VRFs and we then compare with
desired VRFs, instead of assuming it will be just one.
* Add delay and check configuration is right when interfaces is set on eos_vrf
Per the spec we put up for declarative intent modules, we need to check declarative
intent params (in the case of eos_vrf it's 'interfaces') after a delay and non-declarative
params have been set.
If that doesn't meet desired state after delay, we fail the task.
* Check declarative intent param only if config changed
* Fix pep8 issue
* Change default of delay param to 10
* Revert bogus change on eos_vlan
* changed collection arg to argregate on 2.4 network modules
* replace users with aggregate in eos_user, junos_user, nxos_user
* added version_added to places where we replaced users with aggregate in the docs
* fix ios_static_route test
* update tests to reference aggregate instead of collection/users
