FS driver: chunk size is hard-coded

[Lucian Petrut]

At the moment, the filesystem driver uses a hardcoded 64 KB size, used when reading/writing image.

This can be extremely inefficient, especially when file shares are used. For this reason, the chunk size should be configurable, similar to the other glance store drivers.

Could you assign yourself to the bug, and move it to glance_store rather than glance?

@Cyril: Done, thanks for mentioning this. I wasn't aware that glance_store bugs are handled separately, sorry about that.

    Filesystem driver: add chunk size config option

    At the moment, the filesystem driver uses a hardcoded 64 KB chunk
    size, used when reading/writing image files.

    This can be extremely inefficient, especially when file shares are
    used.

    For this reason, this change will make it configurable.
