Disable strict host key checking for ssh session

Because of StrictHostKeyChecking=ask is the default setting in ssh config,
If there is no host key for the server, it will show the fingerprint and
ask to confirm, And because of we already set /dev/null as the user host
key database, the ssh connection always waits for the test scripts answers
"yes" for confirmation. So the test scripts will be blocked at this stage.
(unless the option StrictHostKeyChecking has been disabled in command-line
or /etc/ssh/ssh_config or ~/.ssh/config)

virttest: Make Numa related functions can work on host have disabled node

Now the functions and classes caculate node id by nodes number. And
in a host have disabled node, it may give scripts the disabled node
id. This patch will fix this problem by use available nodes to decide
the node scripts should use.

utils_misc: Update mount check function and fix a wrong arg in umount

When checking mountpoints, the nfs type displays 'nfs4' if mount
version 4 NFS server, so use a regex to search the mount items.
NFS not mounted is not an error, so change the message to debug
level.

Remove umount step as it doesn't make sense to umount in a mount
function.

In the umount function, the second arg in utils.system() is timeout,
so fix it as well. Also, disable verbose by default for
mount/umount/is_mount functions.

virttest.iscsi: Fix a regex and log level

As the newly updated of iscsi related packages, the output of iscsi

searching iscsi device name to adapt the update.

If no iscsi device, it should report error instead of debug msg.

setup_or_cleanup_iscsi: Robust assumptions and pep8 fix

When reviewing jferlan's PR(tp-libvirt#47) to fix vol_create_from case,
i found the problems also exist in setup_or_cleanup_iscsi(), so pick up
the fixes:

When setup iscsi env, the function assumed that the iscsi tools
'tgtadm' and 'iscsiadm' were present on the host which may cause
all sorts of errors and failures. So before running these commands,
make sure the tools exist.

Additionally within iscsi_login, extended testing found that the SCSI
/dev/sdxx device didn't instantaneously appear. Sometimes it took an
extra second or two to appear, so added a loop for get_device_name().

Meanwhile, a pep8 fix to make sure no more combined module imports.
