plugins/hotpages: introduce sortby arg and parsed bool args correctly
Since plugin arguments now expect boolean arguments, a plugin argument name "sortby" now expects a value of "read", "write", or "address". "io" arg is now expected to be passed as a full-form boolean parameter, i.e. "io=on|true|yes|off|false|no" Signed-off-by: Mahmoud Mandour <ma.mandourr@gmail.com> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20210730135817.17816-4-ma.mandourr@gmail.com>

+The hotpages plugin can be configured using the following arguments:

+
+ Log the data sorted by either the number of reads, the number of writes, or
