ENH: suppress display.height DeprecationWarning
related https://github.com/pydata/pandas/issues/4026?source=cc

The `display.height` option is dperecated. It's value is interogated by
`get_conosole_size()`, whose only caller in the codebase summarily ignores
that bit of the `(width,height)` retval.
Another ugly ricochet from the `repr()` cluster***\* of 0.11. a tar pit if ever I saw one.

rather then reprecate (?) the depecrated option (As in #4027), just silence the deprecation 
warning at the root and quickly look away.
