metrics: update produce_summaries to process specific date

[trivikr]

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

The produce_summaries Cloud Run only produces summaries for the previous day

build/ansible/roles/metrics/files/summaries/summaries.js

Lines 96 to 97 in c5c15aa

	let date = moment(new Date())
	date = moment(date, 'YYYYMMDD').subtract(1, 'days').format('YYYYMMDD')

The summaries aren't being produced since 20240502, originally reported in #3697, and an investigation is happening in #3771 to increase request time.

Even if the issue with produce_summaries is fixed, we have to backfill summaries for dates which were missed.

Describe the solution you'd like

Process date parameter in from request params, as pass it to subsequent functions

app.post('/', async (req, res) => {
  await produceSummaries(req.params.date)
  res.status(200).send()
})

This will allow maintainer to request producing summaries for specific dates, like

curl -X POST "https://produce-summaries-kdtacnjogq-uc.a.run.app/?date=20240502" -H "Authorization: Bearer $(gcloud auth print-identity-token)"

Looks like there's an issue with how we processed the GET parameter in express

Source code

curl -X POST "https://produce-summaries-kdtacnjogq-uc.a.run.app/?date=20240401" -H "Authorization: Bearer $(gcloud auth print-identity-token)"

Output

2024-07-02 05:22:40.568 PDT POST 200 116 B 597.6 s curl/8.1.2 https://produce-summaries-kdtacnjogq-uc.a.run.app/?date=20240401

I cannot reopen this closed issue, so created a bug report at #3799
