Creates a new ISBM ProviderRequest client.

 @param endpoint [String] the SOAP endpoint URI
 @option options [Array<String>] :wsse_auth username and password, i.e. [username, password]
 @option options [Object] :logger (Rails.logger or $stdout) location where log should be output
 @option options [Boolean] :log (true) specify whether requests are logged
 @option options [Boolean] :pretty_print_xml (false) specify whether request and response XML are formatted
 Opens a provider request session for a channel for reading requests and
 posting responses.

 @param uri [String] the channel URI
 @param topics [Array<String>, String] a collection of topics or single topic
 @param listener_url [String] the URL for notification callbacks
 @param xpath_expression [String] the XPath filter expression
 @param xpath_namespaces [Array<Hash>] the prefixes and namespaces used by the XPath expression. The hash key
