Propose a common branching strategy for all community repositories

[e-backmark-ericsson]

Description

In order for not re-inventing the wheel I believe it would be good to document a best practice on what branching strategy to use in the Eiffel Community repositories. It should not be mandatory to follow it, but it should be recommended. An example of a branching strategy is currently being discussed through this issue: eiffel-community/eiffel-remrem-semantics#148. That could serve as one alternative when defining a common proposed branching strategy for our repositories.

Motivation

Easier to navigate the Eiffel Community repositories if most of them use the same branching strategy.

Exemplification

Less startup time when initiating a new repository and less frustration when the recommended branching strategy is not defined.

Benefits

See Motivation

Possible Drawbacks

None

It might be the correct place to put this recommendation in the CONTRIBUTING.md file
