18650	combine objects: tag conflict: support more keys with option to sum up values	skyper	team	"==== What steps will reproduce the problem?
1. Have two ways with tag `parking:lane:right:capacity=*`
1. Combine them

==== What is the expected result?
A warning about conflicting tags and the option to open the Tags/Memberships Conflict Dialog where the option to sum up the values is active.

==== What happens instead?
No warning and no sum support.

==== Please provide any additional information below. Attach a screenshot if possible.
While `capacity=*` and `step_count=*` are supported, there are more keys which should be supported when combining ways or merging nodes:
* `parking:lane:right:capacity`
* `*duration*`
* `*volume*`
* `*quantity*`
* `*distance*`

Thanks
