Description

Due to the ">" in https://github.com/idealista/prometheus_server-role/blob/master/templates/prometheus.service.j2#L11, every time Prometheus is restarted it overwrites prometheus.log. It should be replaced with ">>" so it appends the new output to the previous log file.

Steps to Reproduce

Watch prometheus.log file.
Restart Prometheus with systemctl restart prometheus.service
Watch prometheus.log file.

Expected behavior: See both restarts.

Actual behavior: Only last restart appears.

Reproduces how often: Always
