[Policies Plugin] Unsupported criterium type "ServicePrincipalFilterRule"

[CravateRouge]

Hi dirkjanm!

I ran into a little issue when trying the policies plugin:

roadrecon plugin policies -p -d roadrecon.db
...
####################
My Policy Name
97e32d76-dbc0-4cfe-b088-9f37b18743e9
{   'Conditions': {   'Applications': {'Include': [{'Applications': ['All']}]},
                      'Locations': {   'Exclude': [   {   'Locations': [   '044cb1b4-75cc-4b71-9f78-094873583a10']}],
                                       'Include': [{'Locations': ['All']}]},
                      'ServicePrincipals': {   'Include': [   {   'ServicePrincipalFilterRule': 'CustomSecurityAttribute.WorkLoadIDAttributeSet_OnlyStr '
                                                                                                '-eq '
                                                                                                '"yes"'}]},
                      'Users': {'Include': [{'Users': ['None']}]}},
    'Controls': [{'Control': ['Block']}],

              ~~~~~^^^^^^^
KeyError: 'ServicePrincipalFilterRule'

During handling of the above exception, another exception occurred:

Exception: Unsupported criterium type: ServicePrincipalFilterRule

I'm going to holidays now but I may work on a PR later to add this criterium to the plugin
