• https://github.com/opsmill/infrahub/issues/3576
• https://github.com/opsmill/infrahub/issues/3584

Notes:

• Upgrades relationship fields and removes the select 2 steps usage
• If possible, a parent dropdown will allow users to filter nodes from a specific parent
  • for a regular relationship, if the kind is Parent
  • for a generic, if the kind selected has a relationship of kind Parent
  • if the kind selected doesn't allow a parent filter, the select will be disabled
• Adds tooltips for hierarchical dropdowns tips
• Adds prettier-eslint in dev dependencies for formatting purpose
• Aligns labels in forms
