Unable to set client certificate auth using couchbase-cli ssl-manage on 5.1 after multiple path prefixes were implemented

1. Create a couchbase cluster and enable SSL/TLS on the cluster
2. Try to enable the clientCertAuth using the ssl-manage on couchbase-cli
couchbase-cli ssl-manage --set-client-auth-state mandatory -c 10.111.170.101:8091 -u Administrator -p password

The expected behaviour is that we should be able to set the client auth state,prefix, path and delimiter using the couchbase cli. But got ERROR: "Invalid JSON" as output.

We are able to set the clientCertAuth using the rest API (curl -X POST -u Administrator:asdasd -d@client_cert_auth.json http://localhost:8091/settings/clientCertAuth) but not using the couchbase-cli ssl-manage tool.

Tested this on 5.1.0-5547
