AplicationInsightsLoggerProvider does not catch exceptions. #1969

Describe the bug

AplicationInsightsLoggerProvider is not catching exceptions and letting them propagate to caller. This can cause applications to crash if an exception occurs inside ApplicationInsightsProvider. This is against the overall SDK principles of never throwing.

Proposal : catch and log exception to EventSource.
