Need teamd to respawn automatically in RHEL7

Issue

• Teamd is an important daemon that watches and controls active links, if it is killed, we can't do failover any more.
• We would like teamd to respawn if it is killed.

Step to reproduce:

1) Edit ifcfg-team0 , ifcfg-eth0 and ifcfg-eth1

# vi /etc/sysconfig/network-scripts/ifcfg-team0
DEVICE=team0
DEVICETYPE=Team
ONBOOT=yes
BOOTPROTO=none
IPADDR=xxx.xxx.xxx.xxx
NETMASK=xxx.xxx.xxx.xxx
TEAM_CONFIG='{"runner": {"name": "activebackup"}, "link_watch": {"name":
"ethtool"}}'
NM_CONTROLLED=no

# vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=52:54:00:37:5E:BD
DEVICETYPE=TeamPort
ONBOOT=yes
BOOTPROTO=none
TEAM_MASTER=team0
TEAM_PORT_CONFIG='{"prio": 100}'
NM_CONTROLLED=no
UUID=156ee48b-30ce-4873-8507-90ba6df19015

# vi /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=52:54:00:6A:57:4D
DEVICETYPE=TeamPort
ONBOOT=yes
BOOTPROTO=none
TEAM_MASTER=team0
TEAM_PORT_CONFIG='{"prio": 10}'
NM_CONTROLLED=no
UUID=4528902c-2914-4618-bb24-084757878003

2) Activating team0 and check teamd process.

# ifup team0
# ps ax | grep team0
  797  ?        Ss     0:00 /usr/bin/teamd -U -D -t team0 -f /run/teamd/team0.conf

3) Kill teamd process

# kill -KILL 797

Actual results:
- Teamd doesn't restart and we can't do failover any more.

Expected results:
- Teamd automatically restarts.

Additional info:
- It also may be worth considering setting oom_adj by teamd itself.
