Load testing for CoMPAS

[Flurb]

As a PO
I want to know how CoMPAS performs when looking at response times (multiple substations/ multiple versions)
So I know if it's acceptable or not

Background:
The CoMPAS needs to be fast enough for end-users. This can be tested inside the company firewall. If this required we can later added to a public servers and automate this for the community once a need occurs.

Acceptance criteria:
-Document test setup
-Share testsetup with other CoMPAS users
-Build the test script and add it to the repository
-report the error findings in an seperate issue
-Report findings here as well

Typical: 2800 substations x 10 SCD files per substations = over 10k substations
Typical size 50 Megabyte (without compression)

The idea is to use Gatling (https://gatling.io/open-source/) for performance test and robot framework for integration tests. @AliouDIAITE does this sounds good for RTE?
