Expose environment variables with run information in compute nodes

[tnatt]

Is your feature request related to a problem? Please describe.
The environment variables

• _ERT_EXPERIMENT_ID
• _ERT_REALIZATION_ID
• _ERT_SIMULATION_MODE

are not available from the compute nodes.

Describe the solution you'd like
I would like the run information to be available also from FORWARD_MODELS running on the compute node (now it is only available for FORWARD_MODELS during ERT test-run's).

Additional context
Feature introduced in #4904

Which version of ERT did you test this with? 🙂

I did a test in bleeding today before writing the issue (at least I think I did 😄)..

The environment variables

_ERT_EXPERIMENT_ID
_ERT_ENSEMBLE_ID
_ERT_SIMULATION_MODE

They were not designed to be available on the compute node. The feature request #4904 mentioned they should be available on the client. This matches with

it is only available for FORWARD_MODELS during ERT test-run's.

this is because when running the command ert test_run config_file.ert the forward model job will run on the client machine.
