Description

S3AFileSystem.copyFromLocalFile() is lacking some basic checks of arguments (source file exists, do parent directories of dest exist, ...).

The original FileSystem.copyFromLocalFile() codepaths need review to see how they handle such situations, and the S3AFileSystem implementation made consistent. This is best done with an update to the FS Specification and a contract test.
