docs: Executes a query, applying the specified {@link EntityResolver} to the result, using the
  specified {@link TableRequestOptions} and {@link OperationContext}.
  <p>
  This method will invoke a <a href="http://msdn.microsoft.com/en-us/library/azure/dd179421.aspx">Query
  Entities</a> operation on the <a href="http://msdn.microsoft.com/en-us/library/azure/dd179423.aspx">Table Service
  REST API</a> to query the table, using the Table service endpoint and storage account credentials of this
  instance.
  
  Use the {@link TableRequestOptions} to override execution options such as the timeout or retry policy for the
  operation.
  
  @param query
  A {@link TableQuery} instance specifying the table to query and the query parameters to use.
  @param resolver
  An {@link EntityResolver} instance which creates a projection of the table query result entities into
  the specified type <code>R</code>.
  @param options
  A {@link TableRequestOptions} object that specifies execution options such as retry policy and timeout
  settings for the operation. Specify <code>null</code> to use the request options specified on the
  {@link CloudTableClient}.
  @param opContext
  An {@link OperationContext} object for tracking the current operation. Specify <code>null</code> to
  safely ignore operation context.
  
  @return
  A collection implementing the <code>Iterable</code> interface containing the projection into type
  <code>R</code> of the results of executing the query.
