DTS tests - missing the install/update DTS test-cases

[artur-rs]

The problem you're addressing (if any)

Test "DTS005.001 - Flash device from DTS shell by using flashrom works correctly" runs flashrom command instead of using install/deploy DTS function.

Describe the solution you'd like

DTS005.001 test should be reworked, or new test cases for DTS install / DTS update functionality be added.

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

Increase test coverage for DTS functionalities during DTS releases and Dasharo firmware releases.
