Remove send_signal, get_pids, mount and umount
send_signal() is used in _renew_lease_udhcpc() only.
There is not so much merit to keep the method, then this patch just
moves the line into _renew_lease_udhcpc().
Since Ida919c63e27c6a003be4c249ba2e6f3e2ea7a7b3 get_pids() has not
been used. So this patch removes the method.
mount/umount() are only used in scenario manager and they are a single
line command. Many projects still are using these methods, so at this
time this patch just replaces these calls with exec_command() directly
and we will remove these methods after most project will stop using.
