Sporadically a6xx gpu will fail to recover causing the lava job
a660_vk_full to loop on error messages for three hours before timing
out.
A few sporadic error messages may still be recoverable, but when multiple
errors occur over a short period, successful recovery is unlikely. Parse
the logs to look for repeated error messages within a short time period.
If found, cancel the lava job and rerun it.
Also add unit tests for this behaviour.

We were just detecting if a log like
[ 143.080663] r8152 2-1.3:1.0 eth0: Tx status -71
happened once before
[ 316.389695] nfs: server 192.168.201.1 not responding, still trying
But we can use a counter to be more assured that the device is
struggling to recover and we can add let this detection happen during
the boot phase.
This mimics how other freedreno devices deal with this problem, see
`cros_servo_run.py:64` for example.

This commit updates LogFollower class to handle carriage return
characters in LAVA logs. LAVA treats carriage return characters as a
line break, so each carriage return in an output console is mapped to a
console line in LAVA.
The updated LogFollower class now merges lines that end with a carriage
return character into a single line, making the Gitlab sections work
correctly. In addition, the `remove_trailing_whitespace` method has been
updated to remove trailing `\r\n` characters from log lines.
The `test_lava_log_merge_carriage_return_lines` test function has also
been updated to test for carriage returns at the end of the previous
line.
Closes: #8242

Since the Collabora LAVA update related to the downtime from
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/21119, the
LAVA logs from Collabora continued to use the hack for older versions
which digested some control characters, such as carriage returns acting
as newlines, which made it necessary to recover from split lines to make
Gitlab sections work in job logs as expected.
Collabora's LAVA instance now gives a more raw log output. It is
necessary to pay attention to newlines at the end of each log message,
which may cause double newlines when printed with Python built-in
`print` function. I decided to remove the repeating `\n` from the
received log messages to make them transparent to LogFollower users.

LAVA uses XMLRPC to send jobs information and control, more specifically
it sends device logs via YAML dumps encoded in UTF-8 bytes.
In Python, we have xmlrpc.client.Binary class as the serializer
protocol, we get the logs wrapped by this class, which encodes the data
as UTF-8 bytes data.
We were converting the encoded data to a string via the `str` function,
but this led the loaded YAML data to use single quotes instead of double
quotes for string values that made special characters, such as `\x1b` to
be escaped as `\\x1b`.
With this fix, we can now drop one of the hacks that fixed the bash
colors.

Implement a log-based retry hint for R8152 issue described in #6681,
which is based on detecting these two consecutive lines:
```
r8152 <USB> eth0: Tx status -71
nfs: server <IP> not responding, still trying
```
Where <IP> and <USB> could be any IP and USB addresses, respectfully.
This commit is a temporary fix since it requires a section-aware log
follower, implemented in !16323. When the cited MR is merged, one will
make a proper fix on top of that.

In some jobs, such as
https://gitlab.freedesktop.org/gallo/mesa/-/jobs/24904100, the kmsg is
interleaved with stderr/stdout in serial console, making it difficult to
confidently find the log messages to detect when the DUT is booting,
when the DUT is running etc.
Luckily, LAVA sends redundant messages about their signals. We can use
them to mitigate the chance of missing an interleaved message by being
more open to different messages, using the regex on both `debug` and
`target` LAVA log levels.

- Create LogFollower to capture LAVA log and process it adding some
- GitlabSection and color treatment to it
- Break logs further, make new gitlab sections between testcases
- Implement LogFollower as ContextManager to deal with incomplete LAVA
jobs.
- Use template method to simplify gitlab log sections management
- Fix sections timestamps
