Shared boilerplate for :one_for_one DynamicSupervisors that need no
custom init/1 options. Used by PlaidEx.MultiTenant.TenantSupervisor
and PlaidEx.Reliability.CircuitBreakerSupervisor, which are otherwise
identical aside from their child-management functions.
Usage
defmodule MySupervisor do
use PlaidEx.Support.DynamicSupervisorBase
end
