    CertUpdate: make it easy to invoke from other programs
    
    The guts of ipa-certupdate are useful to execute as part of other
    programs (e.g. as a first step of ipa-ca-install).  Refactor
    ipa_certupdate.CertUpdate to make it easy to do that.  In
    particular, make it possible to use an already-initialised API
    object.
