[FIPS][Integration Test] Ensure FIPS-capable Agent can connect to FIPS-capable Fleet Server in an ECH FRH environment

[ycombinator]

What does this PR do?

This PR adds an integration test that ensures that a FIPS-capable Elastic Agent running in an ECH FRH (FedRamp High) environment is able to successfully connect to its own local Fleet Server instance (which, by definition should also be FIPS-capable and running in the ECH FRH environment).

Why is it important?

To ensure that FIPS-capable Agent is able to connect to a FIPS-capable Fleet Server in an ECH FRH environment.
