Fix cfn-init-data path in ignition
The 'local-data' in path /var/lib/os-collect-config/local-data should
be a directory, not a file. However, even if we can fix this, now
os-apply-config will merge configs based on the order [ec2, heat and
local], but actually there is no deployments collected local. Then
unfortunately, the deployments collected from Heat will be
overwriten because the merging order in os-apply-config. At this
moment, we can't change os-apply-config since it's deliberate.
So the only reasonable way we can do now is using
/var/lib/heat-cfntools/cfn-init-data and /var/lib/cloud/data/cfn-init-data.
