Problems:
We do not have an api to update the community details (such as name, description, parent_node_id, and geojson values).

We also do not have an api to delete a community if one is created by accident or is no longer relevant (eg. one community is absorbed into another due to a population shift).

We do currently have the api admin.CreateCommunityReq that creates communities, but it does not allow for editing communities or deleting communities.

Solution
A new api admin.ChangeCommunityReq should be created that allows for updating one or more of these values simultaneously.

Once created, the https://console.couchers.org/admin/ page should be updated to include the new api. This could be a new issue.

Note: If desired, this issue may be split into two issues since there are technically 2 APIs that need to be created (Create vs Delete).
