Enhance collect tool to detect passwordless sudo

Browse Source 
The collect tool expects a password prompt for all sudo operations.
When passwordless sudo is enabled the collect script times out
waiting for a password prompt that never comes.

This update enhances collect tool to detect passwordless sudo
for getting a password prompt on its first sudo operaton and
fails the collect if there is no password prompt.

Test plan:

Verify by enabling  passwordless sudo
PASS:  collect fails with message

Verify by disabling passwordless sudo
PASS: No passwordless sudo passes and collect proceeds
PASS: Collect is rejected when provided with incorrect password
PASS: Verify when ldap is not running
