Subject: [PATCH] [cherry-pick] PR 7013: [Quorum Store] adjust memory and db
 quotas (#7017)

### Description

Set defaults to be suitable for a 100 validator network.

Paraphrasing Sasha:

20000 tps * 1000B (size of a tnx) * 60 s (duration) = 1_200_000_000 bytes
Divide by 100 validator = 12_000_000B each validator ask me to persist on average.

Adding some buffer for peaks:
Memory: 10x - 120_000_000 bytes
Storage 25x - 300_000_000 bytes
