Metrics alert limitation

### Problem Statement

As per the documentation (https://docs.sentry.io/product/alerts/alert-types/#metric-alerts)
Metric alerts are limited to 1000 per organization, as our system requires a more fine tuned monitoring per client (b2c)
and as https://github.com/getsentry/sentry/issues/71239#issuecomment-2125605414, we require a lot more monitoring alerts.
Our system uses micro frontend, so each team needs to have alerts per client which increases the number of alerts exponentially.

Is there a reason why sentry limits to 1000.

### Solution Brainstorm

Increasing the limit beyond 1000.
