Description of problem:
crm_mon -X output does not conform to the schema due to recent changes in bundles. More specifically, allowed values for the type attribute of a bundle element are "docker" and "rkt", while the actual value is "Docker".


Version-Release number of selected component (if applicable):
pacemaker-1.1.18-1.el7.x86_64


How reproducible:
always, easily


Steps to Reproduce:
1. Configure a bundle resource using docker container
# pcs resource show httpd-bundle
 Bundle: httpd-bundle
  Docker: image=pcmktest:http options=--log-driver=journald replicas=3
  Network: host-netmask=24 ip-range-start=192.168.122.145
  Port Mapping:
   port=80 (httpd-port)
  Storage Mapping:
   options=rw source-dir-root=/root/docker/httpd-root target-dir=/var/www/html (httpd-root)
   options=rw source-dir-root=/root/docker/httpd-logs target-dir=/etc/httpd/logs (httpd-logs)
  Resource: apa (class=ocf provider=heartbeat type=apache)
   Operations: monitor interval=10 timeout=20s (apa-monitor-interval-10)
               start interval=0s timeout=40s (apa-start-interval-0s)
               stop interval=0s timeout=60s (apa-stop-interval-0s)

2. Get the status xml and validate it:
# crm_mon -X > state.xml
# jing /usr/share/pacemaker/crm_mon.rng state.xml
state.xml:29:117: error: value of attribute "type" is invalid; must be equal to "docker" or "rkt"
# awk 'NR==29 {print}' state.xml 
        <bundle id="httpd-bundle" type="Docker" image="pcmktest:http" unique="false" managed="true" failed="false" >


Actual results:
The status xml does not conform to the schema.


Expected results:
The status xml conforms to the schema.


Additional info:
This causes issues when pcs works with cluster status xml, for example:
# pcs resource enable dummy
Warning: xml with cluster status does not conform to the crm_mon schema
