Review request for mesos, Yongqiao Wang and Joerg Schad.


Repository: mesos


Description
-------

While writing log or error messages we adhere the following style:
  * No period at the end (there are exceptions though, e.g., one is
    when constructing request responses.
  * When splitting a string over multiple lines, put a space at the
    beginning of the following line in contrast to the end of the
    previous line.
