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.

LavaFarm is a class created to handle the different types of LAVA farms
and their tags in Mesa CI. Since specific jobs may require different
types of LAVA farms to run on, it is essential to determine which farm
the runner is running on to configure the job correctly.
LavaFarm provides an easy-to-use interface for checking the runner tag
and returning the corresponding LAVA farm, making it simple for Mesa CI
to configure jobs appropriately. By adding tests for LavaFarm, the team
can ensure that this class is functioning as expected, allowing for the
smooth execution of Mesa CI jobs on the correct LAVA farm.
The tests ensure that get_lava_farm returns the correct LavaFarm value
when given invalid or valid tags and that it returns LavaFarm.UNKNOWN
when no tag is provided. The tests use Hypothesis strategies to generate
various labels and farms for testing.
Example of use:
```
from lava.utils.lava_farm import LavaFarm, get_lava_farm
lava_farm = get_lava_farm()
if lava_farm == LavaFarm.DUMMY:
# Configure the job for the DUMMY farm
...
elif lava_farm == LavaFarm.COLLABORA:
# Configure the job for the COLLABORA farm
...
elif lava_farm == LavaFarm.KERNELCI:
# Configure the job for the KERNELCI farm
...
else:
# Handle the case where the LAVA farm is unknown
...
```

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.
Closes: #6681

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
