[PATCH datacenter-manager] ui: auto-installer: allow multi-select of installation entries

[Christoph Heiss <c.heiss@proxmox.com>]

Depending on the environment/usage, a lot of entries of past
installations can accumulate here over time.

Having the possibility for bulk deletion makes it easier to deal with
this.
