timelion query bar should be resizable/switch types

[danielmotaleite]

Describe the feature:
timelion query bar should be resizable or switch type to a normal text box.

the timelion queries sometimes can be long and complex and the normal query bar is too small.
That forces the user to open a external editor to edit and change it and then copy&paste to the timelion bar... but even then, small changes or checks requires one to scroll back and forward in the text bar.

pressing a bottom, one could switch the text bar by a resizable text box, where we could put the multiple queries for quick check and change

@danielmotaleite Thanks for creating this issue! I have good news for you... we added multiline support to the Timelion epxression input with #11972. I believe this addresses your concern, so I'm going to close this issue for now. If you'd like to try it out you can build Kibana from master and take it for a spin, or wait for our 6.0.0 release. If we haven't solved your problem, we can always reopen this issue.

That is perfect! thanks for quick feedback and of course, for the feature!

The screen shots look good, so i will wait for the 6.0 release
