Configuration for placing logical/binary operators on previous or next line

[dsherret]

For example, right now the default does this:

const mathResult = 1 + 2 * 6
    + moreMath * math;

But maybe someone would prefer:

const mathResult = 1 + 2 * 6 +
    moreMath * math;

The default should remain the same since it's easier to read though.

Probably "newLineOperatorPosition" or just "operatorPosition" with options "sameLine" and "nextLine" (or maybe "preferNextLine").

Also applies to ternary operators.
