feat: new job wrapper DIRAC Integration

[Loxeris]

Fixes problems related to the execution of the job wrapper on pilots (i.e. cwl ids link to local path).
Also initialize DIRAC in the job wrapper as it's needed to access Dirac Resources (i.e. /Resources/FileCatalogs).

See #44

It's okay for now but just for your information:

• in the current DIRAC code, the initialization is performed in the JobWrapperTemplate: https://github.com/DIRACGrid/DIRAC/blob/11bc43dda994b41832aa29237400f9c2b16c0f2f/src/DIRAC/WorkloadManagementSystem/JobWrapper/JobWrapperTemplate.py#L24
• at some point we want to use the diracx endpoints (Use diracx-api jobs.py module to interact with the sandbox store endpoint (instead of the one from DIRAC) #73). In that case you would need to replace this initialize by providing the DIRACX_URL environment variable in the job_wrapper_template I think.

It seems Script.parseCommandLine() needs to be run before importing any DIRAC component. So the job wrapper template would look like this. If it's ok for you, then it can replace the DIRAC.initialize() without any problem.

from cwl_utils.parser import load_document_by_uri
from cwl_utils.parser.cwl_v1_2_utils import load_inputfile
from DIRAC.Core.Base.Script import Script  # type: ignore[import-untyped]
from ruamel.yaml import YAML

if os.getenv("DIRAC_PROTO_LOCAL") != "1":
    Script.parseCommandLine()

from dirac_cwl_proto.job.job_wrapper import JobWrapper
from dirac_cwl_proto.submission_models import JobModel


def main():
    """Execute the job wrapper for a given job model."""
    if len(sys.argv) != 2:
    ...

It also may change the default logging configuration a bit, but it shouldn't be too much of an issue.

For the DIRACX_URL env var I'm not yet sure how to get the url but I guess we will see when it's needed
