⚗️[RUMF-1351] experiment request retry strategy

[bcaudan]

Motivation

We want to improve our data transfer to:

• limit our impact on end user bandwidth
• not loose data in case of short intake unavailability

Changes

Introduce new request strategy allowing us to:

• limit the number of concurrent requests to the intake -> max 32 by product
• limit the total ongoing bytes of requests to the intake -> max 80kb by product
• retry requests if the intake is momentarily unavailable -> exponential backoff strategy 1s to 256s
• limit the size of queued requests due to throttling or failure -> max 3Mb by product

Behind retry flag, use this new strategy for logs/rum for non exit requests.

Testing

• Local
• Staging
• Unit
• End to end
