memory leaks in data visualization

[davetsay]

Summary

memory leaks need to be addressed

• openmct.components creates a memory leak, is no longer used, and can be removed completely (it was a means to get openmct vue components into plugins developed outside of core openmct)
• plots are not being cleaned up properly (WARNING: Too many active WebGL contexts. Oldest context will be lost.)

Expected vs Current Behavior

Steps to Reproduce

Environment

• Open MCT Version:
• Deployment Type:
• OS:
• Browser:

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?
• Does this block the execution of e2e tests?
• Does this have an impact on Performance?
