Rudder

We have a major performance regression with the display of rule page in rudder 7.0. In our load testing environment, we hit a 5x loading time.

First analysis seems to point to 2 culprits:

- we transfert too much node & groups related data,
- rule status and compliance is painfully slow to get

Some metrics:

- nodes      api:  2 s (    800 ko / 10 500 ko )  (compressed / uncompressed)
- rules      api: 15 s (     23 ko /     84 ko ) 
- directives api:  2 s (     20 ko /    471 ko )
- groups     api:  6 s ( 13 000 ko / 24 700 ko )
- compliance api: 502 (proxy error - likely timeout)
