Ability to re-organize tabs in the metadata schema editor

[#1]

Request for Feature Enhancement (RFE) Summary:	Ability to re-organize tabs in the metadata schema editor
Use-case:	When we want to change the order of the tabs in the metadata schema editor, we will need to delete and create the whole tab page
Current/Experienced Behavior:	AEM metadata schema editor does not allow to re-arrange the header tabs. This is a pain point especially if there are already a lot of changes done in the metadata schema, and we just want to re-arrange the tabs.
Improved/Expected Behavior:	Ability to drag and drop the header tabs to easily arrange them in the order that we want.
