[API] Updates cat and indices endpoints

cat.segments - Adds :master_timeout and :local Boolean parameter: return local information, do not retrieve the state from master node (default: false)
cat.tasks - Adds :timeout and :wait_for_completion parameters
indices.get_field_mapping - Removes :local parameter
indices.resolve_cluster - Adds :timeout parameter, :name no longer a required parameter
