[WIP] Embedded method tree conversion

[jeffibm]

Note: This is an experimental work. Also trying a different approach to avoid the tree structure in another PR.

• Create a AeInlineMethods component to render the list and add method button
• Create a modal to display the tree component.
• Create a MiqTree component
• Create a MiqTreeNode component to display a row in tree
• Create a MiqtreeParentNode to render a parent item
• Create a MiqTreeChildNode to render the child items
• Call the MiqTreeNode component in MiqTreeChildNode as a recursive function to reuse the code
• If one item is selected, only then enable the modals ok button
• Pass the selected item to the AeInlineMethods to add them to the array
• List the items in the AeInlineMethods
• Add a loader near to the selected item
• Style the list
• Make it reusable across MIQ
• Multiselect feature
• checkboxes

Before

• This dialog and its contents were used in angular.

After

• Custom made tree component in React.
• This is not using the old react-wooden-tree package.
