Change datatable type from 'numeric' to 'num' in Mapreduce client App and HS
### Description of PR
Since the use of datatables 1.10, the 'numeric' type doesn't exist anymore
and has been replaced by 'num'. The numeric fields (especially the elapsed
times) were sorted in alphabetical order in the Mapreduce Job History Server
and in the AM interface, making the UI unusable to analyse the performances of
a Mapreduce job.
### How was this patch tested?
Running a Mapreduce job and a Job History server. No additional unit test
was written.
### For code changes:
- [X] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
licensed in a way that is compatible for inclusion under [ASF
2.0](http://www.apache.org/legal/resolved.html#category-a)?
- [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`,
`NOTICE-binary` files?
> Broken sort for numeric columns in UI

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobhistoryserver, webapps, yarn
> Affects Versions: 3.3.6
> Reporter: Alexandre Helmer
> Priority: Major
>
> Some columns the datatables of the UI have the sType "numeric". For instance:
> the elapsed time in mappers or reducers in the Mapreduce job UI, or the
> number of completed mappers/reducers in the Job History.
> However, since the version 1.10 of the datatables library, the type "numeric"
> has been replaced by "num". As a consequence, the columns are now sorted
> lexicographically.
> Replacing "numeric" with "num" fixes the issue.
>
> Tested on version 3.3.6, but I believe it may apply since version 3.1.2.
