    [OVN] Retry retrieving LSP hosting information

    There's a sync issue while trying to fetch the hosting information for
    the LSP before we write it to the OVN database, sometimes the
    information is not yet present and we end up with an empty string ("")
    for the host attribute of portbindings. This patch adds a retry
    mechanism to solve this sync issue.
