TT#38453 Verify remote repository origin in 'check' action (PRO/Carrier)

CE: nothing to be done, no remote present

PRO (both sp1 and sp2):
  Fetch URL: /mnt/glusterfs/ngcpcfg-share
  Push  URL: /mnt/glusterfs/ngcpcfg-share

Carrrier web01a/web01b (mgmt node):
 Fetch URL: /mnt/glusterfs/ngcpcfg-share
 Push  URL: /mnt/glusterfs/ngcpcfg-share

Carrrier db01a/... (non-mgmt nodes):
  Fetch URL: $(cat /etc/ngcp_mgmt_node}:/mnt/glusterfs/ngcpcfg-share
  Push  URL: $(cat /etc/ngcp_mgmt_node}:/mnt/glusterfs/ngcpcfg-share
