    Update docs for serial console support

    There are two changes here:

    1. The serial_console config option group help text is
       updated to point out that hyper-v also supports serial
       console access. This is based on virt drivers that
       implement the 'get_serial_console' method.

    2. The hypervisor feature matrix is updated to point out
       that the vmware driver does not support getting serial
       console output. This is based on virt drivers that
       implement the 'get_console_output' method.

    NOTE(mriedem): Ironic is not listed as a supported driver
    in the serial_console option help text as that support
    was added with c9a64996ecc317b2c05d688e0f5d31c37122ca01 in
    Ocata.
