Doc Text:	.The `nm` provider in the Networking System Role now correctly manages bridges Previously, if you used the `initscripts` provider, the Networking System Role created an `ifcfg` file which configured NetworkManager to mark bridge interfaces as unmanaged. Also, NetworkManager failed to detect followup `initscript` actions. For example, the `down` and `absent` actions of initscript provider will not change the NetworkManager's understanding on unmanaged state of this interface if not reloading the connection after the `down` and `absent` actions. With this fix, the Networking System Role uses the `NM.Client.reload_connections_async()` function to reload NetworkManager on managed hosts with NetworkManager 1.18. As a result, NetworkManager manages the bridge interface when switching the provider from `initscript` to `nm`.	Story Points:	---

Description Wen Liang 2021-12-22 13:19:33 UTC

Description of problem:

The system role build `rhel-system-roles-1.7.3-2.el7_9` CI gating failed on
`tests_ethernet_nm.yml` (https://dashboard.osci.redhat.com/#/artifact/brew-build/aid/41866280?focus=id:7faf82018486-1)
and the failures indicated that the the created veth device is strictly unmanaged even if we explicitly set it to managed.

```
nmcli d set lsr27 managed yes

Dec 20 19:39:10 ibm-p8-kvm-03-guest-02.virt.pnr.lab.eng.rdu2.redhat.com NetworkManager[738]: <info>  [1640047150.4781] audit: op="device-managed" arg="managed" pid=19292 uid=0 result="success" (Journal)

(nmcli d)
DEVICE     TYPE      STATE         CONNECTION  
eth0       ethernet  connected     System eth0
peerlsr27  ethernet  disconnected  --          
lsr27      ethernet  unmanaged     --          
```

The situation arised only when the last test playbook is  `tests_ethernet_initscripts.yml`, when initscripts provider ran, the connection profile (/etc/sysconfig/network-scripts/ifcfg-lsr27) contained `NM_CONTROLLED=no`, which indicated that the device lsr27 is not managed by NM and at the end we cleaned the device and profile then when NM provider ran, we have to reload the connection because the connection profile was deleted (changed) previously. The test palybooks `tests_auto_gateway_nm.yml`, `tests_ipv6_nm.yml`, `tests_vlan _mtu_nm.yml` ran into the same issue. 


Version-Release number of selected component (if applicable):
rhel-system-roles-1.7.3-2.el7_9

How reproducible:
Always


Steps to Reproduce:
1. Download rhel-guest-image-7.9-30.x86_64.qcow2 from http://download.hosts.prod.upshift.rdu2.redhat.com/released/rhel-6-7-8/rhel-7/RHEL-7/7.9/Server/x86_64/images/rhel-guest-image-7.9-30.x86_64.qcow2

2. `sudo TEST_DEBUG=1 TEST_SUBJECTS=rhel-guest-image-7.9-30.x86_64.qcow2 ansible-playbook -v -i /usr/share/ansible/inventory/standard-inventory-qcow2  ./tests/tests_ethernet_initscripts.yml ./tests/tests_ethernet_nm.yml`


Actual results:
Errors: "state:up persistent_state:present, 'lsr27': up connection failed: failure to activate connection: nm-manager-error-quark: No suitable device found for this connection"


Expected results:
No errors

:: [ 02:24:21 ] :: [   PASS   ] :: Test network/tests_ethernet_initscripts.yml (roles/rhel-system-roles.network/tests/tests_ethernet_initscripts.yml) with ANSIBLE-2.9 against RHEL_7_9_GA (Expected 0, got 0)
:: [ 02:25:38 ] :: [   PASS   ] :: Test network/tests_ethernet_nm.yml (roles/rhel-system-roles.network/tests/tests_ethernet_nm.yml) with ANSIBLE-2.9 against RHEL_7_9_GA (Expected 0, got 0)

[root@netqe18 Upstream-testsuite]# rpm -q rhel-system-roles
rhel-system-roles-1.13.0-1.el8.noarch
[root@netqe18 Upstream-testsuite]#

now the tests_ethernet_nm.yml playbook can pass after running tests_ethernet_initscripts.yml. Set this to verified
