Fix errors for "host set" command

Huanxuan Ao · Huanxuan Ao · commit 7177014fcc14 · 2016-06-22T14:20:53.000+08:00
"Host set" command cannot work. Because:
1.Host has no 'ID' attribute, so 'ID' attribute cannot be found
in "host set" command.
2.value "True" and "Flase" are invalid in updata() method of host.
3.Some update functionalities is not supported in host API now.

This patch solves the problems 1 and 2 in OSC. But the problem 3
is a API problem and can't be solved in OSC, only XenServer driver
support to set enable/disable and maintenance host, it is a normal
problem.
After this patch the output of "host set" command is:
The requested functionality is not supported. (HTTP 501)
(Request-ID: req-14031fce-8c90-48a0-8492-dc8e3dd349f3)
Just the same as the "host-update" command in novaclient.
