Demoting some of the non-warning messages to notice (#10715)

We have cases where we print information (might be important but by
no means an error indicator) with the LL_WARNING level.
Demoting these to LL_NOTICE:
- oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
- User requested shutdown...

This is also true for cases that we encounter a rare but normal situation.
Demoting to LL_NOTICE. Examples:
- AOF was enabled but there is already another background operation. An AOF background was scheduled to start when possible.
- Connection with master lost.


base on yoav-steinberg's https://github.com/redis/redis/pull/10650#issuecomment-1112280554
and yossigo's https://github.com/redis/redis/pull/10650#pullrequestreview-967677676
