SetupTimeIntegratorAction

Add a TimeIntegrator object to the simulation.

A TimeIntegrator is specified as an object inside the [TimeIntegrator] block with the [Executioner] block as shown below

[Executioner]
  type = Transient
  dt = 1
  num_steps = 3

  [TimeIntegrator]
    type = NewmarkBeta
  []
  [Quadrature]
    type = GAUSS
    order = FIRST
  []
[]

This MooseObjectAction adds them to the Problem. More information about TimeIntegrators may be found on the TimeIntegrator syntax documentation.
