Allow merging of Credentials
----------------------------

                 Key: HADOOP-8048
                 URL: https://issues.apache.org/jira/browse/HADOOP-8048
             Project: Hadoop Common
          Issue Type: Improvement
          Components: util
    Affects Versions: 0.24.0, 0.23.1
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


There is an existing {{Credentials#addAll}} which combines two {{Credentials}}, but it overwrites all existing {{Credentials}}.  There should be a {{Credentials#mergeAll}} that will not overwrite.  This will facility the cleanup of code in {{TokenCache}} denoted with:
{code}
//TODO: Need to come up with a better place to put
//this block of code to do with reading the file
{code}

The token cache basically needs to merge the contents of a binary credentials file when it fails to find a token.  Performing the merge within {{Credentials}} is cleaner, and will break the cross-component dependency whereby the {{TokenCache}} currently has to have intimate knowledge of how the {{FileSystem}} will key tokens in the cache.
