Remove flush method on LogEmitter

[srikanthccv]

Fixes #2342

Changes

This change proposes to remove the flush on Emitter for the consistency. There is no flush on Tracer/Meter specification. Language sdk implementations may choose the idiomatic way to provide the appender/handler ability to call flush on the LogEmitterProvider (ex: setter in java, init arg in py, or possibly a global accessor for provider etc...)

LGTM, but also need confirmation at least from @jack-berg

[jack-berg]

I'm in favor of removing the flush method as originally discussed here 👍
