Create temp_url for LPs uploaded to swift

[Murali Allada]

Languagepacks created today and stored in swift for one tenant are not accessible by another tenant. This blocks the usecase where a developer wants to use an operator created languagepack.

We need to change the way we store a reference to the build languagepack. If we create temp_urls for the LP in swift, it can be downloaded by anyone who has access to the LP id.

    Create temp_url for LPs uploaded to swift

    Languagepacks created today and stored in swift for one tenant are not
    accessible by another tenant. This blocks the usecase where a developer
    wants to use an operator created languagepack.

    We need to change the way we store the reference to a
    languagepack in the DB. If we create temp_urls for the LP in swift, it
    can be downloaded by anyone who has access to the LP id.
