GH-2253: Revert (S)FTP Source to DefaultDirScann

Browse Source 
Fixes spring-projects/spring-integration#2253

For backward compatibility and use-cases when processed files are stored
in sub-directories in the `localDirectory` revert the
`AbstractInboundFileSynchronizingMessageSource` logic back to the
`DefaultDirectoryScanner`.
The `RecursiveDirectoryScanner` can be injected via `scanner` option

Also the `AbstractInboundFileSynchronizingMessageSource` can now be switched to the `WatchService` -based `DirectoryScanner` via `setUseWatchService()` option.
It is also configured for all the `WatchEventType` s to react for any modifications in local directory.
The reprocessing sample above is based on the build-in functionality of the `FileReadingMessageSource.WatchServiceDirectoryScanner` to perform `ResettableFileListFilter.remove()` when the file is deleted (`StandardWatchEventKinds.ENTRY_DELETE`) from the local directory.

The Inbound Channel Adapters now have a property `max-fetch-size` which is used to limit the number of files fetched during a poll when there are no files currently in the local directory.
They also are configured with a `FileSystemPersistentAcceptOnceFileListFilter` in the `local-filter` by default.
You can also provide a custom `DirectoryScanner` implementation to Inbound Channel Adapters via the newly introduced `scanner` attribute.
The regex and pattern filters can now be configured to always pass directories.
