This patch adds the required parameters to the Compute role so the
agents are configured properly on upgrade.

# A Heat environment file that enables DVR in the overcloud.
# This works by configuring L3 and Metadata agents on the
# compute nodes.

# Enabling DVR deploys additional services to the compute nodes that through
# normal operation will consume memory. The amount required is roughly
# proportional to the number of Neutron routers that will be scheduled to
# that host. It is necessary to reserve memory on the compute nodes to avoid
# memory issues when creating instances that are connected to routed
# networks. The current expected consumption is 50 MB per router in addition
# to the base reserved amount. Deployers should refer to existing
# documentation, release notes, etc. for additional information on estimating
# an appropriate value. The provided value here is based on an estimate of 10
# routers and is an example value *only* and should be reviewed and modified
# if necessary before deploying.
