[pbs-devel] [PATCH v4 proxmox-backup 6/6] ui: add option to change the maintenance type

The renderer is set in the init function because a context where view is
accessable was needed. Since only the renderer function needs this
context the rest of the 'maintenance-type' row is defined declaratively.
I also tried to somehow inject the active operations values into the
store, since its passed to the renderer function, but that seemed a little
'hacky'.
