Currently, Amphora configuration data is being sent as personality
files as considered by Nova and some providers have limitations
and must use cloud-init user-data.
This patch introduces a new config option to enable user-data.
If enabled the files that were built, such as the amphora config
and certificates for the agent, will be templated into a cloud-init
user-data script that loads the files as expected. After this we
need to restart the agent as cloud-init happens at a higher level
than service scripts. This does increase the boot time.
This is configurable so there is no impact if it's not needed.
