Adding time synchronization to network boot tests

[mysteriousCzrsX]

The problem you're addressing (if any)

Network boot tests PXE004.001 DTS option is available and works correctly and PXE005.001 OS installation option is available and works correctly. Require that the system boots over IPXE using https. When the system time is not synchronized, the https connection would fail, thus the tests would not be completed.

Describe the solution you'd like

We could synchronize time prior to running the tests by using ntp command in iPXE shell. Command is described here.

Where is the value to a user, and who might that user be?

This would save time when running test since now to properly run the tests a manual time synchronization procedure must be performed.

Describe alternatives you've considered

An alternative method of time synchronization is booting in to the operating system and using its tools to synchronize the system clock.

Many header and Suite inits are mess of multiple keywords and formatting. Perhaps this suite is another one that could benefit greatly from isolating initialization into local keyword. We could also force network sync in the local init keyword.
