Exclude Azure´s AlwaysOn calls

[pmierzwa]

Is your feature request related to a problem?
Using Azure´s "Always On" feature pings "/" every 5 minutes. This fills up my applications insights with messages that has no use to me. It also shows up in the application map, which then gives me a false number for the amount of requests.

This path cannot be excluded in the OPENCENSUS EXCLUDELIST_PATHS, is it is using a string.startswith()

opencensus-python/opencensus/trace/utils.py

Lines 45 to 70 in d63d295

	def disable_tracing_url(url, excludelist_paths=None):
	"""Disable tracing on the provided excludelist paths, by default not tracing
	the health check request.
	If the url path starts with the excludelisted path, return True.
	:type excludelist_paths: list
	:param excludelist_paths: Paths that not tracing.
	:rtype: bool
	:returns: True if not tracing, False if tracing.
	"""
	if excludelist_paths is None:
	excludelist_paths = DEFAULT_EXCLUDELIST_PATHS
	# Remove the 'https?|ftp://' if exists
	url = re.sub(URL_PATTERN, '', url)
	# Split the url by the first '/' and get the path part
	url_path = url.split('/', 1)[1]
	for path in excludelist_paths:
	if url_path.startswith(path):
	return True
	return False

Describe the solution you'd like.
I would like some sort of pattern to exclude the Azure AlwaysOn feature. Eg. ["!!AzureAlwaysOn"].

Describe alternatives you've considered.
I would be able to use [""] as a EXCLUDELIST_PATHS, but that would exclude everything.

Additional context.
Using Django.

The Azure AlwaysOn call example: http://localhost:8000/ eg. GET /

Hi,
any progress on this?

At work we are using the FastAPI extension to log to Azure Insights and the Azure pings to “/“ are really cluttering our logs.

I would be very grateful for a solution or workaround on this.
