These include the owned pods, containers, and details view plugin
renderer sections.

This will be useful to understand e.g. why pods are pending.

This allows us to show the controlled jobs, the schedule with a
human-readable description, etc.

The last scheduled time was not using the "time ago" way and therefore
was very confusing. This patch also adds an icon to the schedule
(cron) with a description of it on hover.

There was a bug where such statuses were being shown with the warning
theme.

Fix windows app not closing server.exe on quit

There's a margin in WSL because it has problems placing
full size windows.

This is useful as it is but also will satisfy the linter (which
complains that the template plugin's registry argument is not
used).

The lib.ts file should carry the bits to be used by plugins whereas
the index.ts should have the functions that Headlamp itself needs for
loading the plugins.

This is just about tidying up the module a bit.

Instead of using a fixed headlamp-plugin version when creating a new
Headlamp plugin, we should use the same version of the headlamp-plugin
module.

This class allows to call registerPlugin from itself which is more
convenient than using "window.".
