Time strip views should only allow time-based plots, imagery and plans

[shefalijoshi]

Non time based plots, other object types and layouts are currently allowed in time strip views. These should not be allowed.

Steps to Reproduce

1. Try to add a display layout, condition set, bar graph etc to a time strip view
2. Notice that this is allowed

Environment

• Open MCT Version: 2.0.3
• Deployment Type: VIPER/testathon

Impact Check List

• Data loss or misrepresented data?
• Regression? Did this used to work or has it always been broken?
• Is there a workaround available?
• Does this impact a critical component?
• Is this just a visual bug with no functional impact?

Testing instructions:
Adding plots, overlay plots, stacked plots, plans, imagery should work for timestrips.
