Remove right-click option Display Metadata

[backmari]

Description of work:

The table right-click option "Display Metadata..." causes the GUI to crash. According to the IS, this functionality is not used and can be removed.

Check all that apply:

• added release notes (if not, provide an explanation in the work description)
• updated documentation
• Source added/refactored
• Added unit tests
• Added integration tests
• Verified that tests requiring the /SNS and /HFIR filesystems pass without fail

Manual test for the reviewer

(instructions to set up the environment)

Start RefRed GUI

(refred)> PYTHONPATH=$(pwd):$PYTHONPATH ./scripts/start_refred.py

Or run tests

(refred)> pytest test/unit/RefRed/test_main.py

Check list for the reviewer

• release notes updated, or an explanation is provided as to why release notes are unnecessary
• best software practices
  • clearly named variables (better to be verbose in variable names)
  • code comments explaining the intent of code blocks
• All the tests are passing
• The documentation is up to date
• code comments added when explaining intent
