Add possibility to reduce the metadata simultaneous download
For some reason installer freezes on some machines when metadata
download amount exceeds certain limit. Currently it is limited to 1000
simultaneous requests and this has solved the issue previously but now
the issue has recurred. Added a environment variable IFW_METADATA_SIZE
so user can decrease the download amount to prevent freezing.
