No Check of Management Strategy

[weibullguy]

When checking the feasibility of a reliability growth test plan, the management strategy isn't checked. Add this check and use the following to set the risk levels:

- < 0.9 => high risk
- > 0.95 => high risk
- 0.9 - 0.925 => medium risk
- 0.925 - 0.95 => low risk
