Replace repo-reinst with kraken, handle in UIs

[HebaruSan]

Background

When you refresh the registry, if the metadata for one of your installed modules has been changed upstream, CKAN will ask whether you want to reinstall those modules, and if you say Yes, it will reinstall them.

The following mods have had their metadata changed since last update:

- Buffalo v2.9.0
- WildBlueTools v1.81.5
- ExtraPlanetaryLaunchpads 6.8.3.0
- ClassicStockResources v1.1.4

You should reinstall them in order to preserve consistency with the repository.

Do you wish to reinstall now?

Problems

If one of your installed modules has been updated to have a new dependency on a virtual module, the reinstall fails:

Failed to connect to repository. Exception: Too many mods provide Buffalo-PlayMode:
* Buffalo-PlayMode-CRP v2.10.2
* Buffalo-PlayMode-ClassicStock v2.10.2
* WildBlue-PlayMode-Pristine v1.82.1
* WildBlue-PlayMode-Simplified v1.82.1
* WildBlue-PlayMode-USI v1.0.0.2

Causes

Repo.HandleModuleChanges creates its own ModuleInstaller to try to do the reinstall.

When a dependency on a virtual module is found, ModuleInstaller (via other classes) throws TooManyModsProvideKraken. The UI is supposed to catch this, prompt the user, add the module they chose to the change set, and try again. However, this is impossible in the case of a repo-reinstall, because the UI does not know what changes Repo.HandleModuleChanges was attempting to make and cannot retry the repo update to fix it.

Changes

Now instead of initiating a half-hearted attempt at doing a reinstall itself, Repo.HandleModuleChanges throws a new ReinstallModulesKraken to instruct the UI-specific calling code to reinstall the given modules. Cmdline, ConsoleUI, and GUI are updated to catch this exception and launch into their upgrade flows for the given modules.

Now ConsoleUI and GUI perform upgrades after installs, so the installs (which contain the user's choice of virtual module providers) can satisfy dependencies needed by the upgrades.

As a side fix, Cmdline's ckan upgrade command is updated to handle prompting for virtual module providers (in a shared function also now called by the repo update code as needed).

Fixes #1889.
Fixes #3335.

Nice, works perfectly!
