Description

When attempting to add a custom storm-site property which is a YAML map of maps, the storm.yaml file being generated is incorrectly escaping the map.

"Expected YAML"

nimbus.impersonation.acl:
storm:
  hosts:
    [c6401.ambari.apache.org, c6402.ambari.apache.org]
  groups:
    [hadoop, foo]

"Actual YAML"

nimbus.impersonation.acl: 'storm:
  hosts:
    [c6401.ambari.apache.org, c6402.ambari.apache.org]
  groups:
    [hadoop, foo]'

• We should not be escaping YAML maps
• YAML maps must being on a newline with no leading whitespace
