Allow a single Swarm per single team

Currently there are no much filters over the dashboards and forms.

However, to separate the services we will introduce projects. With project may come namespaces or environments (not yet decided).

This way, each page/form will require to have, at least, 3 additional, and dependent on each other, filters.

To fight the complexity, it makes sense to limit the flexibility of the service.

Users should not be able to create multiple swarms per team.

This should also help with the separation of access roles for larger companies. Many will want to have a dedicated "staging" environment where "everyone" will be do everything and a "production" environment where only specific people would be able to make changes.

Separating these two into different swarms AND teams will simplify UI & UX by a lot.

As a side note, consider creating multiple swarm clusters per team as a feature for "business" plans only.
