Plugin complains that EventHub name does not meet requirements when storage container has an underscore

[mbrancato]

The plugin will fail and provide the following error when the storage_container value does not conform to an EventHub name.

The error will look like:

 {:event_hub_name=>"valid-eventhub-name", :exception=>java.lang.IllegalArgumentException: EventHub names must conform to the following rules to be able to use it with EventProcessorHost: Must start with a letter or number, and can contain only letters, numbers, and the dash (-) character. Every dash (-) character must be immediately preceded and followed by a letter or number; consecutive dashes are not permitted in container names. All letters in a container name must be lowercase. Must be from 3 to 63 characters long., :backtrace=>["com.microsoft.azure.eventprocessorhost.AzureStorageCheckpointLeaseManager.initialize(com/microsoft/azure/eventprocessorhost/AzureStorageCheckpointLeaseManager.java:112)", "com.microsoft.azure.eventprocessorhost.EventProcessorHost.registerEventProcessorFactory(com/microsoft/azure/eventprocessorhost/EventProcessorHost.java:464)", "java.lang.reflect.Method.invoke(java/lang/reflect/Method.java:498)", "org.jruby.javasupport.JavaMethod.invokeDirectWithExceptionHandling(org/jruby/javasupport/JavaMethod.java:423)", "org.jruby.javasupport.JavaMethod.invokeDirect(org/jruby/javasupport/JavaMethod.java:290)", "usr.share.logstash.vendor.bundle.jruby.$2_dot_3_dot_0.gems.logstash_minus_input_minus_azure_event_hubs_minus_1_dot_0_dot_4.lib.logstash.inputs.azure_event_hubs.block in run(/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-input-azure_event_hubs-1.0.4/lib/logstash/inputs/azure_event_hubs.rb:430)", "org.jruby.RubyProc.call(org/jruby/RubyProc.java:289)"...

While the same rules apply to blob containers, the error is saying (and showing) the valid EventHub name, not the container name.
