Is your feature request related to a problem? Please describe.
if I have a baggage header like:

corp.key1=val1;tag2;tag3

String result = Baggage.current().getEntryValue("corp.key1");
// result is "val1"

If I want the additional data, I have to write code like:

String result = Baggage.current().asMap().get("corp.key1").getMetadata().getValue()
// result is "tag2;tag3"

Describe the solution you'd like
I'd like an additional API:
Baggage.current().getEntry() that returns the BaggageEntry
