Customize HTTPJSON record for Elastic

[jgphpc]

• Use https://reframe-hpc.readthedocs.io/en/stable/tutorial.html#customizing-the-json-record to cast all integer perf values to float for Elastic (Update slurm tests returned perf_values #380)
• Share the command line used to run the test

any test that use int as perf. value

common.py prints data["check_perf_value"]:

P: elapsed_min: 7 s (r:0, l:None, u:None)
7.0 <-------- check_perf_value

which is what I want (int -> float) BUT

jq .runs[0].testcases[0].perfvalues latest.json

will return 7

and

jq . httpjson_record_*.json

will return "check_perf_value": 7,

instead of 7.0

Same issue with check_perf_ref

⚠️ ⚠️ ⚠️ jq version matters:
💣 jq-1.6 .* httpjson_record_1759920609851.json |grep check_perf_value

 "check_perf_value": 107,    # WRONG

✅ ./jq-1.8.1 .* httpjson_record_1759920609851.json |grep check_perf_value

  "check_perf_value": 107.0, # OK

Pull Request Overview

This PR customizes the HTTPJSON record formatting in ReFrame to ensure integer performance values are cast to float type for Elastic compatibility. The change addresses an issue where performance values were being serialized as integers in JSON output despite being converted to floats in the data processing.

• Implements a custom JSON formatter function to explicitly cast check_perf_value and check_perf_ref to float
• Adds debug output and configuration to use the custom formatter in the HTTPJSON logging handler

@jgphpc , as far as I can tell, the custom httpjson formater works as expected. It will not change what is in the json report, only what reframe sends to elastic. And you can see that happens in the httpjson_record_<ts>.json files, when debug is enabled. At least it looks like it's working for my test. 🤔 Could you send me a specific test that produces an int in httpjson_record_<ts>.json?
