```
The issue is that `webDir` not yet created by `HistoryServer` when
`HistoryServerArchiveFetcher` tries to reach `jobs/overview.json` file in it.
The directory will be created later on so this PR is to eliminate the initial
issue.
## Brief change log
* `webDir` is now created in the constructor of `HistoryServer`
* Double `webDir` creation in `HistoryServer.start` is eliminated
* `HistoryServerArchiveFetcher` now throws `IOException` if `webJobDir` or
`webOverviewDir` creation if failed.
