allow configuration of throttling rate and time unit

[the-clam]

New PR; accidentally discarded the commits for the branch used for the old PR: #7540

modified OtlpConfigUtil.java to take in:

otel.exporter.otlp.lograte
otel.exporter.otlp.throttledlograte
otel.exporter.otlp.logtimeunit

and configure the necessary values to set the log rate and throttled log rate for ThrottlingLogger.Java

Since the new configurations are for logs, would it be better under otel.exporter.otlp.logs.*?

Will wait for the others to get back to me before I make changes for that, comments were left in an older PR that wasn't working properly: #7540 (comment)

let's separate the programmatic configuration from the property-based one. I think @jack-berg is going to prefer that this get built into the new file-based configuration system, rather than adding new env vars/properties at this point.
