upload report directory to the server

[gyorb]

Upload not just the plist reports but the whole reports directory to help debugging.

Should be able to configure in the server_config,json where the compressed report directory should be stored.

{
"report_dir_store": "/some/path",
...
}

If the report_dir_store is not configured in the server config file the client should not send the compressed report directory.

The compressed report directories should be stored separately for each product and run.

/some/path/myproduct1/myrun1-report-dir.zip
/some/path/myproduct1/myrun2-report-dir.zip
/some/path/myproduct2/myrun2-report-dir.zip

Keep only the last report directory zip for each run.
