kannankvs 4007d9ba9c [ntp]: modified ntp script to hide the error related to cfggen (#3745)
This PR is to handle the issue 3527.
When device boots up, NTP throws a traceback as explained in the issue 3527.

- Traceback will be seen when MGMT_VRF_CONFIG does not exist in the database. Traceback is coming from the script “/etc/init.d/ntp”.

- Traceback does not affect the NTP functionality with/without management VRF. When MGMT_VRF_CONFIG does not exist or when MGMT_VRF_CONFIG’s mgmtVrfEnabled is configured to “false”, “NTP” will be started in the “default VRF” context, which is working fine even with this traceback.

- This traceback error will be hidden by redirecting the error to /dev/null without affecting functionality.

# 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.
