    Added priorities for centos extra repos

    We need to be able to download packages from
    various repositories taking into account repository
    priority. We need this for patching story.

    By default priorities are
    1) upstream 90
    2) proprietary 20
    3) DENY_RPM_DOWNGRADE=1 (default: 1), we are
       not allowed to downgrade rpm packages. In some
       cases when we need to be able to use downgraded
       versions this flag should be set to 0:
          DENY_RPM_DOWNGRADE=0

    EXTRA_RPM_REPOS is to have the following format
        "name1,url1,pri1 name2,url2,pri2"

    In case when pri is not defined it will be set to 10,
    for example:
        "name1,url1" is equal to "name1,url1,10"
