Now replay jobs will respect the original job failfast option, when used. Also,
it is possible to disable failfast option on replay jobs with `--failfast off`.

Avocado already logs when process is executed, it could be useful to
also know when the process finishes. Note it's not immediately after the
process finishes, but it's logged when avocado notices the process
finished.

Currently when the process time-outs, it's killed by default with
SIGTERM and then the status is reported. This usually results in process
returning non-zero status, which is then reported to the user. The
problem is that SIGTERM can be caught and handled inside the executed
command and it can report 0. Then the user does not know whether the
command actually finished on time or whether it was killed by avocado.

This commit sets the `self.result.interrupted`, which makes sure the
status is propagated even when the process finishes with zero.

Currently the interrution is hardcoded to be ctrl+c (signal) only. This
patch uses the `self.result.interrupted` as interruption reason, which
should allow different types of interruptions.

The interrupted message lacked '' around the cmd and ignored the

  avocado.utils.asset raise exception when not able to fetch asset

Currently asset fetcher returns path to the asset file or None
when it fails to fetch it. This patch makes it o raise an exception
in such cases.

The aexpect module is used by the Docker plugin.  Since we do not

The `expire` argument was added later and there are usecases where it

The main change is actually incorrect, the kernel.py library uses
`data_dirs` argument to determine the `cache_dirs`, which is by default
`self.work_dir`.

avocado/plugins/journal.py: make the goal of this plugin more clear

We found some users of this plugin, and we're unsure they actually use
this as intended.  Even if they don't use it as intended, it may be a
good thing, *but* we should make it clear what was the original goal
of this feature.

Use the avocado.utils.filelock to avoid race conditions:
 - Download the files with a temporary unique name.
 - Lock the original file.
 - Move downloaded file to the original name.
 - Compute the hash, creating the hashfile.
 - Verify the file against the provided hash.
 - Unlock the original file.
 (While the lock is acquired, users trying to use the file will wait until
 the lock is released or, on wait timeout, receive a cache miss)

Drop EnviromentError exceptions on cache miss. Instead, we now only
log an error message and return None.

Clean debug messages. Log was being polluted by asset fetcher. Let's
make it quieter.

This is a general purpose file locker.

If the lock file already exists and it contains the current process
id in it, we wait until the timeout for the lock to be released,
raising an AlreadyLocked exception when the timeout is reached.

If the lock file already exists and it contains a pid of another
running process, we raise an AlreadyLocked exception.

If the lock file exists and it has no running processes pid in it,
we try to clean the file and acquire the lock, raising a LockFailed
exception when something goes wrong.
