KUDU-1388: Master web UI should show table's partition schema

This patch adds PartitionSchema::DisplayString that creates a pretty-printed
string suitable for display, and changes the web UI to display this string on
/table.

The format is

Hash bucket schemas:
  Key columns:
    name_s00 type_s00
    name_s01 type_s01
    ...

  Key columns:
    name_s10 type_s10
    name_s11 type_s11
    ...

  ...

Range columns:
  name_r0 type_r0
  name_r1 type_r1

The display on the web UI is naive and it won't, e.g., display Unicode
characters correctly, but that's true of the web UI in general and a fix
should probably wait until after KUDU-981.
