azure-monitor-opentelemetry distro should configure event provider

[lmolkova]

OTel events are not captured by default. A workaround:

from opentelemetry._events import set_event_logger_provider
from opentelemetry.sdk._events import EventLoggerProvider

configure_azure_monitor()
event_provider = EventLoggerProvider()
set_event_logger_provider(event_provider)

@lzchen @jeremydvoss wdyt given that event API is merged into logs and won't last long?

We would probably want to include this as part of the distro. It might not be a good idea to recommend users to manually use experimental apis (especially ones that will disappear soon).

I am okay with this. But we should put in in a try-catch. (In fact, we should do the same for the logs imports now that I think about it.)
