Ported svnTests to latest svn plugin version.

Marked classes and methodes only used by the deprecated test class also as deprecated.

Tidied up docker container and its dependencies.

Changed svn docker user to "svnUser" to prevent possible name overlaps.

 Fixed some typos, messages and jdoc
Tweaked test cases to prevent errors caused by to fast test execution
Permit test harness to use http proxy settings

[JENKINS-23069] A bit nicer way of sanity checking

There are several problems:

1) Checking after navigation is not enough as it is triggered only if navigating explicitly via WebDriver. Clicking links/buttons is not covered.
2) Sanity checking need to access page source witch triggers UnhandledAlertException in case alert is present, in firefox alert is dismissed at this point.
3) Checking if alert is present upfront (`driver.switchTo().alert()`) is hideously slow (1-2 seconds).

Moving the check to #beforeClickOn and #beforeNavigateTo so it is no longer necessary to handle alerts (any alert present at this point is clearly unhandled). We can add checking to #onException at any time.

This fixes DiskUsagePluginTest#reflect_disk_changes_in_disk_usage_report (problem #2).
