Installs a Multi to Single Point Intent
Description:
Install a multi to single point intent using
add-multi-to-single-intent
Steps:
- Fetch host data if not given
- Add multi to single intent
- Ingress devices are the senders devices
- Egress device is the first recipient host
- Ports if defined in senders or recipients
- MAC address ethSrc loaded from Ingress device
- Check intent state with retry
Required:
name - Type of point intent to add eg. IPV4 | VLAN | Dualstack
senders - List of host dictionaries i.e.
[ { "name":"h8", "device":"of:0000000000000005/8","mac":"00:00:00:00:00:08" } ]

Optional:
onosNode - ONOS node to install the intents in main.CLIs[ ]
0 by default so that it will always use the first
ONOS node
ethType - Ethernet type eg. IPV4, IPV6
bandwidth - Bandwidth capacity
