Result view - include label/name in tooltip

[janfh]

Fixes #380

Adds a second line in the tooltip when hovering the result view header that includes label or name depending on what is used in the header.

warning: manager.ts is modified to enable extended metadata by default (this is the same behaviour as ACS).

@janfh I tried this today but I can't seem to get the label to show. What am I missing?

LABEL ON COLUMN SNDBX87.DEPARTMENT (deptno is 'department number');

SELECT * FROM SNDBX87.DEPARTMENT as a;

@worksofliam : Can you please verify that extended metadata is enabled for the connection?

[worksofliam]

@janfh I can confirm it is.

@janfh I just noticed there is no change to manager.ts in this PR!

I see it come through when I set it manually:

@worksofliam : Looks like I managed to revert extended metadata when merging from master. Appears to be working now, but I can test it some more

[worksofliam]

@janfh i will test again. Thank you!

Looking good! I also tested the label showing in the title and that is working as expected also.
