fix: state listener observe writes at wrong time (backport #13516) (#…

…14138)

* fix: state listener observe writes at wrong time (#13516)

* fix: state listener observe writes at wrong time

Closes: #13457

Currently state listener is notified when the cache store write, which happens in commit event only, which breaks the current design.
The solution (as discussed in the issue) is to listen state writes on rootmulti store only.

It also changes the file streamer to output single data file for the writes in the whole block, since we can't distinguish writes from different stage of abci events.

It adds new config items for file streamer:
- streamers.file.output-metadata
- streamers.file.stop-node-on-error
- streamers.file.fsync

* synchronous abci call, and format doc

* fix comment

* update file streamer readme and fix typos

* typo

* improve UX of file streamer, make it immediately usable after enabled

- set default value to write_dir.
- make write_dir based on home directory by default.
- auto-create the directory if not exists.

* get homePage from opts

 ### API Breaking Changes
 
+* (store) [#13516](https://github.com/cosmos/cosmos-sdk/pull/13516) Update State Streaming APIs:
+    * Add method `ListenCommit` to `ABCIListener`
+    * Move `ListeningEnabled` and  `AddListener` methods to `CommitMultiStore`
+    * Remove `CacheWrapWithListeners` from `CacheWrap` and `CacheWrapper` interfaces
+    * Remove listening APIs from the caching layer (it should only listen to the `rootmulti.Store`)
+    * Add three new options to file streaming service constructor.
+    * Modify `ABCIListener` such that any error from any method will always halt the app via `panic`
 * (store) [#13529](https://github.com/cosmos/cosmos-sdk/pull/13529) Add method `LatestVersion` to `MultiStore` interface, add method `SetQueryMultiStore` to baesapp to support alternative `MultiStore` implementation for query service.
 
 ### Bug Fixes
 
 * (baseapp) [#13983](https://github.com/cosmos/cosmos-sdk/pull/13983) Don't emit duplicate ante-handler events when a post-handler is defined.
 * (baseapp) [#14049](https://github.com/cosmos/cosmos-sdk/pull/14049) Fix state sync when interval is zero.
+* (store) [#13516](https://github.com/cosmos/cosmos-sdk/pull/13516) Fix state listener that was observing writes at wrong time.
