The current implementation will crash if the connection fails as the
`time` module is not imported. Fix the import problem. While here,
tweaks the connection to wait progressively when the connection fails.

The avocado.Test class, used as the basis of the avocado_qemu.Test
class, performs a clean of temporary directories up as part of its own
tearDown() implementation.
But the avocado_qemu.Test class is currently missing the same clean
up, as it implemented its own tearDown() method without resorting to
the upper class behavior.
This brings avocado_qemu.Test behavior in sync with the standard
avocado.Test behavior and prevents temporary directories from
cluttering the test results directory (unless instructed to do so with
Avocado's "--keep-tmp" option).

This patch adds a test for record/replay, which boots Linux
image from the disk and interacts with the network.
The idea and code of this test is borrowed from boot_linux.py
This test includes only x86_64 platform. Other platforms and
machines will be added later after testing and improving
record/replay to completely support them.
Each test consists of the following phases:
- downloading the disk image
- recording the execution
- replaying the execution
Replay does not validates the output, but waits until QEMU
finishes the execution. This is reasonable, because
QEMU usually hangs when replay goes wrong.

raise QMP errors in the form of Python exceptions.

private execution interface that will ease transition churn. However, I

HMP command "change vnc" can take the password as argument, or prompt
for it:
(qemu) change vnc password 123
(qemu) change vnc password
Password: ***
(qemu)
This regressed in commit cfb5387a1d "hmp: remove "change vnc TARGET"
command", v6.0.0.
(qemu) change vnc passwd 123
Password: ***
(qemu) change vnc passwd
(qemu)
The latter passes NULL to qmp_change_vnc_password(), which is a no-no.
Looks like it puts the display into "password required, but none set"
state.
The logic error is easy to miss in review, but testing should've
caught it.
Fix the obvious way.
