Prevent power measurement errors failing any tests. Monitor also drops in measurement frequency: A warning of unusually low measurement frequency will be shown in the power plot in case of drop in the measurement frequency. This can help in detecting any problems in the measurement hardware. Signed-off-by: Samuli Leivo <[email protected]>

Create keywords and tools for starting recording power measurement and extracting measurement data from the measurement agent. This PR does not yet apply the power measurement keywords. Application examples can be found in:
https://github.com/leivos-unikie/ci-test-automation/tree/power_measurement_test
https://github.com/leivos-unikie/ci-test-automation/tree/power_measurement_test2
IP address to measurement agent can be given from command line or from test_config
Login credentials to measurement agent have been added to ghaf-infra (https://github.com/tiiuae/ghaf-infra/pull/327/files). Running locally would require that you provide the credentials as variables via command line and comment out the respective line in variables.robot.

This enables usage of power measurement in ci-test-automation so that the test setups missing power measurement HW are not affected.The power measurement tooling monitors also measurement frequency:
