Shouldn't we also flush the "full" batch when we try to write the storages?

The important one is the delete-flush, since it may be unbounded (extremely large). The things we hold in memory are bounded by the memory limits of the difflayers.

Cherry pick bug fixes from upstream for snapshots, which will enable higher transaction throughput. It also enables snapshots by default (which is one of the commits pulled from upstream). Upstream commits included: 68754f3 cmd/utils: grant snapshot cache to trie if disabled (ethereum#21416) 3ee91b9 core/state/snapshot: reduce disk layer depth during generation a15d71a core/state/snapshot: stop generator if it hits missing trie nodes (ethereum#21649) 43c278c core/state: disable snapshot iteration if it's not fully constructed (ethereum#21682) b63e3c3 core: improve snapshot journal recovery (ethereum#21594) e640267 core/state/snapshot: fix journal recovery from generating old journal (ethereum#21775) 7b7b327 core/state/snapshot: update generator marker in sync with flushes 167ff56 core/state/snapshot: gethring -> gathering typo (ethereum#22104) d2e1b17 snapshot, trie: fixed typos, mostly in snapshot pkg (ethereum#22133) c4deebb core/state/snapshot: add generation logs to storage too 5e9f5ca core/state/snapshot: write snapshot generator in batch (ethereum#22163) 18145ad core/state: maintain one more diff layer (ethereum#21730) 04a7226 snapshot: merge loops for better performance (ethereum#22160) 994cdc6 cmd/utils: enable snapshots by default 9ec3329 core/state/snapshot: ensure Cap retains a min number of layers 52e5c38 core/state: copy the snap when copying the state (ethereum#22340) a31f6d5 core/state/snapshot: fix panic on missing parent 61ff3e8 core/state/snapshot, ethdb: track deletions more accurately (ethereum#22582) c79fc20 core/state/snapshot: fix data race in diff layer (ethereum#22540) Other changes Commit f9b5530 (not from upstream) fixes an incorrect default DatabaseCache value due to an earlier bad merge. Tested Automated tests Testing on a private testnet Backwards compatibility Enabling snapshots by default is a breaking change in terms of the CLI flags, but will not cause backwards incompatibility between the node and other nodes.

We've seen some high memory usage on Ropsten around block 6M when snapshots are enabled. Our hunch is that there might be some huge contract self-destruct that takes it's toll on the memory usage. This PR is a benchmark test to see if that's indeed the case or not.
