Fix Ethernet privileges

Post method:
  1) /redfish/v1/Managers/bmc/EthernetInterfaces/<str>/VLANs/
     ConfigureComponents -> ConfigureManager

Patch method:
  1) /redfish/v1/Managers/bmc/EthernetInterfaces/<str>/VLANs/<str>/
     ConfigureComponents -> ConfigureManager

  2) /redfish/v1/Managers/bmc/EthernetInterfaces/<str>/
     ConfigureComponents -> ConfigureManager (SubordinateOverrides)

Delete method:
  1) /redfish/v1/Managers/bmc/EthernetInterfaces/<str>/VLANs/<str>/
     ConfigureComponents -> ConfigureManager

This change allows only Admin user to post, patch, and delete on VLAN
Network Interface Collection and restrict Operator user.
Same for the EthernetInterfaces patch method.

Tested: Ran curl test with admin and operator privileged user for
        all methods (post, patch, and delete). one test failing.

Error: curl -k -H "X-Auth-Token: $bmc_token"  -X PATCH -d
       '{"VLANId" :30 , "VLANEnable" : true}'
       https://${BMC_IP}/redfish/v1/Managers/bmc/EthernetInterfaces/
       eth0/VLANs/eth0_50

       This command is unable to update the VLANId value. instead, it
       deletes VLAN
