Feature #4151551: TFS plugin refactor streamer.py file

[Miryam-Schwartz]

What

1. Create a seperate file for each class located in the streamer.py file
2. Remove the data fetching in the Prometheus format
3. Remove the inline args usage from the flow
4. Break the UFMTelemetryStreaming class into more granular classes

Why ?

https://redmine.mellanox.com/issues/4151551.
Remove unused functionality and break large file into smaller ones.

How ?

_
Break the UFMTelemetryStreaming class into three classes:

1. TelemetryParser: Handles fetching the telemetry data, parsing, processing, and caching it in a map.
2. TelemetryAttributesManager: Updates the saved/cached attributes (headers) when the telemetry data is parsed.
3. Streamer: Streams data to Fluentd using either the HTTP protocol or the FORWARD protocol
