Make the workflow work with an InfluxDB Cloud instance

[elliotfontaine]

Right now, since the workflow uses the influx ping command, the following occurs:

Error: InfluxDB OSS-only command used with InfluxDB Cloud host
2024-06-14T11:19:06+02:00 CRITICAL - failed/ERR

According to Influx doc, this command doesn't work with the cloud version of their database.

Possible solutions:

• Remove the ping_influxdb_server task, since there will be an error at the create_run_bucket one anyway if the workflow can't access the database.
• Use graph branching and check in the log for the specific error.
