Creates a new LinearRetryPolicyFilter instance.
@class
The LinearRetryPolicyFilter allows you to retry operations,
using an linear back-off interval between retries.
To apply a filter to service operations, use `withFilter`
and specify the filter to be used when creating a service.
@constructor
@param {number} [retryCount=3]            The client retry count.
@param {number} [retryInterval=30000]     The client retry interval, in milliseconds.

@example
var azure = require('azure-storage');
var retryOperations = new azure.LinearRetryPolicyFilter();
var blobService = azure.createBlobService().withFilter(retryOperations)
