    hostgenerator-m3: make profile optional
    
    Previously, if a user wanted a host to use the default hardwareProfile
    that is defined in the `hostgenerator-m3` function, they had to
    specify `hostProfile: default` in their host catalogue.
    
    With this change, the profile may simply be ommitted, in which case
    the default profile will be used automatically.
