Subject: all: add patch to minimize unnecessary logs

Currently, running default otelopscol (opentelemetry-operations-collector)
will thrown the errors as described in [1].

This patch fix it by removing scraper "process" and "processes" from
hostmetrics and by changing default log level from "info" to "error".
