Handle noisy simulators for Delay gate

**Describe the feature you'd like**
Delay gate should not necessarily be an identity gate in noisy simulations, but instead may result in noise proportional to the length of the delay.

**How would this feature be used? Please describe.**
For example, delay may be used in dynamical decoupling sequences. When running a noisy simulation, the delay operation should actually produce noise on the target qubit(s) rather than just being simulated as an identity.

**Describe alternatives you've considered**
