title: Error with chromedriver version. Protractor require 2.31
body: <p>I think the Protractor is looking for the last available version of chromedriver, 2.31. The version was release the 22th of July 2017, 2 days ago. I cannot use this version because it is not compatible with my centos version (GLIBC_2.18).</p>
  
  <p>Any way the chrome site says that the last release is the chromedriver 2.30.
  So why protractor try to use the 2.31 ? This version is not installed.
  Is there a way to force the use of a specific version ?</p>
  
  <p>Thanks.</p>
