schematics_state data source JSON output

[stevestrutt]

The ibm_schematics_state data source output state_store does not output in a usable format. To be usable state_store should be outputted in JSON format equivalent to the standalone statefile format.

Currently it seems to be Terraform internal format turned into one long string.

map[lineage:6a4245a2-994a-7306-32ef-fe8d17ed2a35 outputs:map[backend_server_host_ip_addresses:map[type:[tuple [[tuple [string]]]] value:[[172.17.0.4]]] bastion_host_ip_addresses:map[type:[tuple [string]] value:[52.116.132.36]] frontend_server_host_ip_addresses:map[type:[tuple [[tuple [string string]]]] value:[[172.16.0.5 172.16.2.5]]]] resources:[map[instances:[map[attributes:map[architecture:amd64 crn:crn:v1:bluemix:public:is:us-south:::image:r006-e0039ab2-fcc8-11e9-8a36-6ffb6501dd33 id:r006-e0039ab2-fcc8-11e9-8a36-6ffb6501dd33 name:ibm-centos-7-6-minimal-amd64-1 os:centos-7-amd64 status:deprecated visibility:public] schema_version:0]] mode:data name:os provider:provider.ibm type:ibm_is_image] map[instances:[map[attributes:map[architecture:amd64 crn:crn:v1:bluemix:public:is:us-south:::image:r006-e0039ab2-fcc8-11e9-8a36-6ffb6501dd33

For Ansible dynamic inventory integration it needs to be in JSON format equivalent to the standalone format. An additional use case is backup of the statefile, which would also need to be JSON. The simplest solution would be to add a new output which is in JSON format.

@smjtd works perfectly thanks.
