When we start or restart the heat-agent, we run
configure_container_agent.sh which writes a few scripts. Make sure that
the scipts do not exist before writing to avoid overwriting any values
created on runtime.
When the heat-agent starts, /etc/os-collect-config.conf includes only
the reference to the os-refresh-config command. After the agent
bootstap, this file contains the credentials to check for software
deployments in the [heat] section. Before this patch, when the agent
restarted /etc/os-collect-config.conf was cleared resulting the agent to
stop working. I have the survive restarts, skiping only
os-collect-config.conf should be enough, but it is better to not touch
files on just service restart.
Additionally, fix file permissions for /etc/os-collect-config.conf.
Change heat-container-agent tag to ussuri-dev.
