There are some problems of cluster_size=0 on RHEL.6 host and which will not be fixed,
so remove this scenario on RHEL.6 host.

qemu.tests: drop case "balloon_check_qmp".

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1324342

1. case logic is wrong, there are 2 types in the configuration, 1 is balloon_check, the other is kernel_install, actually kernel_install is the case which will be executed.
2. no need to match qmp output pattern now.
3. balloon_check_qmp steps can be covered in balloon_check with qmp, and no scenario about kernel_install and balloon_check.

1. block_hotplug.cfg: add separate scenario for repeated plug/unplug, no need repeat 300 times for each scenario when one pci.
2. block_hotplug.py: get and close a separate session when using it to fix file descriptor out of range problem.
3. stop_continue.py: close session when test finished.

drive_mirror: Remove mirroring  to qcow2 on iscsi.

When drive mirroring with qcow2 image on iscsi, it will cause mismatch issue, which is caused by iscsi instead of qemu,
so only test raw image on iscsi, qcow2 matrix will be covered with local and nfs storage.

Update /dev/hwrng to /dev/random for rng random read

need to read from /dev/random instead of /dev/hwrng

/dev/random is the place from where you should always read
/dev/hwrng will be available to read if you have a hardware rng
device
