ziti edge update service-policy to empty/no posture checks fails

[dovholuknf]

Issue:

ziti edge create service-policy test Dial -p "#test" --output-request-json

see the posture check role:

ziti edge list service-policies 'name contains "test"'
╭────────────┬──────┬──────────┬───────────────┬────────────────┬─────────────────────╮
│ ID         │ NAME │ SEMANTIC │ SERVICE ROLES │ IDENTITY ROLES │ POSTURE CHECK ROLES │
├────────────┼──────┼──────────┼───────────────┼────────────────┼─────────────────────┤
│ .iOx0fOlV1 │ test │ AllOf    │               │                │ #test               │
╰────────────┴──────┴──────────┴───────────────┴────────────────┴─────────────────────╯

issue and see postureCheckRoles: null:

ziti edge update service-policy test -p "" --output-request-json
PATCH to https://__controller__:18441/edge/management/v1//service-policies/.iOx0fOlV1
{
    "postureCheckRoles": null
}

get the token and issue curl, replacing null with []:

curl -k -X PATCH -H "Content-Type:application/json" -H "zt-session:42297671-7190-4023-ae6f-15c8a8f1a999" https://ec2-18-188-201-183.us-east-2.compute.amazonaws.com:18441/edge/management/v1/service-policies/.iOx0fOlV1 -d '{"postureCheckRoles": []}'
{"data":{},"meta":{}}

now check and posture checks are gone from the policy:

ziti edge list service-policies 'name contains "test"'
