OTA Requestor and Provider fixes (#10037)
Browse files Browse the repository at this point in the history 
* Fix for 9525: Close the BDX ExchangeContext when transfer is over

* Fix for 9478: Add configuration for sending "Busy" status and DelayedActionTime

Add the following command line options to the Provider Linux executable:
-q/--QueryImageBehavior <UpdateAvailable | Busy | UpdateNotAvailable>
          Status value in the Query Image Response
-d/--DelayedActionTimeSec <time>
        Value in seconds for the DelayedActionTime in the Query Image Response

* Address PR comments: Rename fields, add a log message.

Also revert to treating AckEOFReceived as an unexpected event on the Downloader

* Move gOtaFilepath declaration to be with the rest of CLI argument global variables

* Address review comment: Close the exchange in the additional error cases

* Restyled by clang-format
