Disable crawler in FS/NAS gateway mode (#9695)
No one really uses FS for large scale accounting usage, neither we crawl in NAS gateway mode. It is worthwhile to simply disable this feature as its not useful for anyone. Bonus disable bucket quota ops as well in, FS and gateway mode

#### Usage crawler
|
||||
Data usage crawler is enabled by default, following ENVs allow for more staggered delay in terms of usage calculation.
|
||||
Data usage crawler is enabled by default on erasure coded and distributed erasure coded deployments.
|
||||
|
||||
The crawler adapts to the system speed and completely pauses when the system is under load. It is possible to adjust the speed of the crawler and thereby the latency of updates being reflected. The delays between each operation of the crawl can be adjusted by the `MINIO_DISK_USAGE_CRAWL_DELAY` environment variable. By default the value is `10`. This means the crawler will sleep *10x* the time each operation takes.
