Enhance the download feature

[Mahesha-M]

Currently, software module downloads feature, downloads the requested file to the work directory, perform checksum and file size check and then copies from work directory to target location (which is known only by the software update module). Later it also clears the work directory.

Since after executing download, software module only sends the status message with progress, state and software module name and version but it never says in which location it is saved.

I would recommend that it is good to publish one last message saying where the file is saved.

Use case: Consider one peripheral device (uC or Bluetooth module or any module) is attached to the host and one software application is taking care of interfacing between the peripheral and the host. The software application also has capability to perform peripheral module software update.

In this case if the software module broadcast the downloaded file artifacts along with path, then this software application can be able to pick the file and perform the peripheral software update.
