Add aviary metadata to the dashboard and add ability to copy cell values

[hschilling]

Summary

This PR adds showing Aviary variables metadata as a hover over popup in the Aviary Variables Tab of the dashboard.

It also adds Copy buttons to cells so the user can easily copy the values and paste them into Python code.

Finally, it adds a checkbox that lets the user only show Aviary Variables in the table. ( Variables whose promoted names begin with "mission:" or "aircraft".)

The easiest way to see and test this is:

python ./aviary/examples/external_subsystems/simple_weight/run_simple_weight.py
aviary dashboard run_simple_weight

Then look at the Results-Aviary Variables Tab.

Test:

1. Hover over first 3 columns to see hover over popup
2. Try the Show Only Aviary Variables checkbox
3. Try clicking on the Copy buttons to see if they copy the correct values in the correct format for use in Python code

would it be possible to have the "copy" button not not grab the quotation marks?
If you copy a name and then paste it into the search/filter at the top, it will give you no results unless you delete the quotes

I love this! I played around a bit, I like that the arrays are immediately ready for numpy after copying them. Thanks Herb!

Looks like there might be an issue with the line wrapping?
I confirmed that the description in metadata has the proper spacing.
