[ENH] - Allow passing verify=False to WorkflowService

[viniciusdc]

Context

When running the scheduler in more complex contexts such as nebari, if the main host endpoint for the Argo service is behind a proxy whose DNS has a self-signed certificate, any requests made via Hera will lead to the following issue:

Tried it, failed with : HTTPSConnectionPool(host='nebari-static.cmreclimatechange.nsf', port=443): 
Max retries exceeded with url: /argo/api/v1/workflows/dev 
(Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: 
self-signed certificate (_ssl.c:1006)')))

The corresponding WorkflowService class already allows such configuration:
https://github.com/argoproj-labs/hera/blob/3470e8e8ec6f416d66e1e9a2a35970f3cbcf1261/src/hera/workflows/service.py#L63-L72
which already supports the check for the required setting in the global_config object as well:

self.verify_ssl = verify_ssl if verify_ssl is not None else global_config.verify_ssl

We need to make sure our authenticate function is extended to allow such settings as well:

argo-jupyter-scheduler/argo_jupyter_scheduler/utils.py

Lines 53 to 73 in 5dea3f7

	def authenticate():
	namespace = os.environ["ARGO_NAMESPACE"]
	if not namespace:
	namespace = "dev"
	token = os.environ["ARGO_TOKEN"]
	if token.startswith("Bearer"):
	token = token.split(" ")[-1]
	base_href = os.environ["ARGO_BASE_HREF"]
	if not base_href.endswith("/"):
	base_href += "/"
	server = f"https://{os.environ['ARGO_SERVER']}"
	host = urljoin(server, base_href)
	global_config.host = host
	global_config.token = token
	global_config.namespace = namespace
	return global_config

Value and/or benefit

Addresses issue when running both services in a local (testing) environment

Anything else?
