monitor/hmp: add support for flag argument with value
Adds support for the "-xs" parameter type, where "-x" denotes a flag
name and the "s" suffix indicates that this flag is supposed to take
an arbitrary string parameter.
These parameters are always optional, the entry in the qdict will be
omitted if the flag is not given.

[FE: fixed typo pointed out by Eric Blake
use s instead of V to indicate string parameter]
