Increase wait timeout for service endpoints reconfig

Install/bootstrap HP EL8000 as subcloud timed out, while
waiting for endpoints reconfiguration to complete
during bootstrapping.

This server has a single processor which takes around 9 mins
to apply the runtime manifest, which is greater timeout
value than 450 seconds. In general, everything is slower on this
particular hardware, e.g. install is slower and cli commands
take almost twice longer to complete than other servers.

This update increases the endpoints reconfiguration wait
timeout to 720 seconds which provides a safety margin.

Testcases:
Install/bootstrap HP EL8000 as a subcloud.
