Add new parameter to recovery_1st_stage_command and recovery_2nd_stage_command.

The new parameter represents the primary (main) server host name which
is defined in backend_hostname parameter. The commands used to obtain
the host name by using hostname command. This is usually fine but in
some systems the host name returned by hostname command is not same as
backend_hostname. This brings problem to detach_false_primary feature.

Note that documentations are not completed in this commit because of
my development environment (Ubuntu 20) issue (openjade crashes). I
will push document changes later using another PC.
