It makes sense to report swap and memory in the same unit and MiB is
more useful considering Home Assistant may be running on lower end
hardware (Raspberry Pi for example) where 100MiB resolution is not
adequate.
Adds an empty unit to load averages reported by the systemmonitor
component in order to correctly identify the state as numeric.
A similar workaroud to this is already used for packet counts in the
same component.
Re #11022
* Fix duplicate entity_ids in System Monitor
This fix makes it so `_percent` is appended to the `entity_id` of the following 3 resources, in order to make the `entity_id` unique:
- disk_use_percent
- memory_use_percent
- swap_use_percent
* match entity_id to resource name
Match entity_id to resource name, to make resulting entity_id more predictable
* match entity_id to more resource names
match entity_id to more resource names
* Add unique_id property
* Revert "Add unique_id property"
