InfluxDB configuration script fails when upgrading influxdb.conf

[Swann Croiset]

when patching the InfluxDB configuration to disable HTTP logs, the script used to create users/database/rentention policy fails because it is executed after that InfluxDB is restarted but not yet ready to accept HTTP requests: connection refused

This works the first installation but that fails while the plugin is upgraded from 0.8.0 to 0.8.1.

    Retry to execute script to configure InfluxDB

    The script is executed after the influxdb service is started but
    InfluxDB doesn't accept HTTP requests directly at start time. This should
    depend on the size of the DB.
