[PULL 06/10] python/aqmp: Reduce severity of EOFError-caused loop terminations

[John Snow]

When we encounter an EOFError, we don't know if it's an "error" in the
perspective of the user of the library yet. Therefore, we should not log
it as an error. Reduce the severity of this logging message to "INFO" to
indicate that it's something that we expect to occur during the normal
operation of the library.
