security/test_bmc_network_security.robot requires sudo for ICMP

[generatz]

security/test_bmc_network_security.robot uses nping with ICMP. ICMP creates a raw socket, which requires root privilege / sudo.

At a minimum, this should be mentioned in the Documentation on the second line of the file.
I'd also like to see a check in the appropriate test's Setup that verifies that the EUID is 0.
And perhaps the script should be split in two, putting the tests that require sudo into a separate script for safety and convenience.

Thanks @generatz for the feedback..

Documentation, we should definitely add, as for the script to handle, I ll let @prkatti1 take a call on it.

Looked into it, will add the documentation for which TCs we need sudo privileges.
For 1 or 2 TCs we'll not have separate suite, will leave it to user to have proper infrastructure before running it.(New Documentation will help here).
