software/ors-amarisoft: Improve eNB xlog forwarding

Make some adjustements to the eNB instance of the ors-amarisoft software release to facilitate eNB log forwarding to Wendelin Telecom:

• Add a tag to the ORS xlog-fluentbit configuration to uniquely identify the ORS, which is published in the connection parameters for easy retrieval. This tag has the format <hostname>_<computer>_<radio_id>, where <radio_id> is set as e<enb_id> or g<gnb_id>, depending on which is defined. Such a tag provides sufficient identifying information and is unique.
• Add file state tracking to the tail input section of the fluentbit instance. Without it, fluentbit reads the log file from head every time it is restarted (with Read_from_Head set to true), which leads to data duplication on Wendelin and ingestion of data that is out of chronological order, messing up the KPI graphs and data size optimizations.
