[llvm] [libc++] Temporarily increase the number of extra attempts for the benchmark cron (PR #217839)

[Louis Dionne via llvm-commits]

https://github.com/ldionne created https://github.com/llvm/llvm-project/pull/217839

We've had instability on lnt.llvm.org lately due to bots crawling the server without it being a CDN and it going down. We also enabled https from the user to the Fastly CDN, which led to some jobs failing since they were trying to submit using http instead of https.

All of this resulted in a few commits reaching their number of max attempts without having 3 samples each. To make up for the missing runs in LNT, this patch temporarily increases the extra attempts so the system will submit jobs for the missing data automatically.

We should be able to revert this patch in roughly 1 day once the missing commits have data.

Subject: [PATCH] [libc++] Temporarily increase the number of extra attempts
 for the benchmark cron

We've had instability on lnt.llvm.org lately due to bots crawling the
server without it being a CDN and it going down. We also enabled https
from the user to the Fastly CDN, which led to some jobs failing since
they were trying to submit using http instead of https.

All of this resulted in a few commits reaching their number of max
attempts without having 3 samples each. To make up for the missing
runs in LNT, this patch temporarily increases the extra attempts so
the system will submit jobs for the missing data automatically.

We should be able to revert this patch in roughly 1 day once the
missing commits have data.
