[UI & UX] Increase component size for namespaces dropdown

[rmeloca]

What would you like to be added

For a large cluster with many namespaces is quite painful to switch between namespaces due to the really tiny size of the component.
It would be nice IMO to have it three times larger.

Why is this needed

To enhance User Experience when switching between namespaces

[floreks]

That's basically why the input field works as a filter, so that user don't have to scroll forever to find the namespace. It is also the default size defined by the material design. We really don't like to override their defaults if this isn't absolutely necessary.

[rmeloca]

I do not disagree with you,
but it is just annoying to me having to leave my mouse just go to the keyboard to type the namespace I want and then switch back to my mouse.

[nneul]

The material design "defaults" are broken in my view if they result in something this badly formatted.

The height of the alarm panel isn't anywhere near that short - why is the namespace list so short - and why so much excessive padding around every line.

.mat-select-panel {
   max-height: 600px;
}

by itself is a huge improvement in usability. Absent a code change - is there any good/easy way to add custom CSS during deployment?
