We need to be able to provide "verify=False" to ignore SSL certificate
and "cert= path_to_cert_bundle" to
provide a custom certificate authority bundle while creating the connection with SalesforceStreamingClient.
By default it has Verify= True and Cert = None and its reading the cert from REQUESTS_CA_BUNDLE environment variable location and fails if there is no cert there. SalesforceStreamingClient does not take any parameter to override verify and cert values.
Thanks for your help.
