[confgenerator] Implement LoggingReceiverTCP in Otel Logging.

[franciscovalentecastro]

Description

Implement LoggingReceiverTCP in Otel Logging. Some details :

• The tcplogreceiver [1] in Otel determines a log ends after finding a "new line character".
• This differs from the Fluent-bit tcp receiver which can parse multiple json entries without any separation of a new line. This receiver directly builds a JSON entry from the TCP byte stream.
