Show human readable error messages when creating component fails

Closes #3520071

This MR:

• Adds client side validation for invalid formats (422 error response)
  • button is disabled until input is valid
  • added unit tests for validateMachineNameClientSide
• Renders the human-readable message of the JSON response (409 error response)
• Created new feature folders for validation and error-handling since we will probably add more in the future.
• Added html-react-parser library to render HTML to the user for when the error response contains HTML tags like <em/>
