[network-manager-applet/th/vpn-service-info-bgo767197: 2/2] c-e: allow one VPN plugin to create multiple "Add" entires



commit a185bc9483d4ae0b6fc899261ac7c778b57e1cdd

    c-e: allow one VPN plugin to create multiple "Add" entires
    
    Previously already, one VPN plugin could edit connections with different
    service-types, using aliases. That is for example used for nm-libreswan,
    which supports both libreswan and openswan types.
    
    However, in "Connection Add" one plugin could only create one entry
    in the list of supported types. Thus, the vpn.service-type could
    only be set to the main service-type, and one plugin could not create
    different types.
    
    Extend that, by allowing the VPN to specify that it supports adding
    of connections also for alias types.
