-h shortcut seems to be not working for xtrabackup

[Shahriyar Rzayev]

Hi,

./xtrabackup --version
./xtrabackup version 2.3.6 based on MySQL server 5.6.24 Linux (x86_64) (revision id: 02d8b7a)

[shahriyar.rzaev@qaserver-04 bin]$ ./xtrabackup -h
./xtrabackup: option '-h' requires an argument
[shahriyar.rzaev@qaserver-04 bin]$ ./xtrabackup -hlocalhost
xtrabackup: Error: unknown argument: '-hlocalhost'
[shahriyar.rzaev@qaserver-04 bin]$ ./xtrabackup -h localhost
xtrabackup: Error: unknown argument: 'localhost'

But -u and -p are OK:

[shahriyar.rzaev@qaserver-04 bin]$ ./xtrabackup -uroot -pBaku12345# --backup

-h cannot be assigned for --host option because it was always assigned for --datadir in xtrabackup.

Message "./xtrabackup: option '-h' requires an argument" should however be fixed.
