METRON-1176 Rest support for setting permissions on files written by
HdfsService
This PR adds support to the HdfsController and HdfsService to optional set
the permissions on files written to hdfs.
Three new parameters, one each for user, group, and other mode are passed,
in the form of symbolic permission strings ('rwx','r-x','r--').
If **any** of the three are missing, no permission override will be
executed.
If **any** of the three are not valid, and exception will be thrown.
##Testing
[ ] Build, tests should run
[ ] Full Dev, Swagger, use the HdfsController post, and set the
permissions, don't set the permissions, set invalid permissions
[ ] Verify files, for example a good place to write to is
"/apps/metron/patterns/NAME"
[ ] In the metron ui, testing grok patterns should work
```bash
> vagrant ssh
> sudo su -
> hdfs dfs -ls /apps/metron/patterns
```
