Added source interface support for NTP. Also made NTP start on Mgmt-VRF by default when configured. **- How I did it** 1) Updated hostcfg to listen to global config NTP and NTP_SERVER tables and restart ntp when ever the configuration changes. NTP table includes source interface configuration. 2) The ntp script updated to by default start on Mgmt-VFT when configured. Signed-off-by: Prabhu Sreenivasan <prabhu.sreenivasan@broadcom>

# This file was originally created automatically as part of default NTP application installation from debian package.
|
|
# This is now manually modified for supporting NTP in management VRF.
|
|
# When management VRF is enabled, the NTP application should be started using "cgexec -g l3mdev:mgmt".
|
|
# Check has been added to verify the management VRF enabled status and use cgexec when it is enabled.
|
|
# This file will be copied on top of the etc/init.d/ntp file that gets created during build process.
