Use shlex from standard library which splits arguments properly instead of
implementing our own buggy version.

Sometimes it's not enough, as we can guess from the tests failures.

See merge request nexedi/slapos.toolbox!84

We don't really care how long DNS resolution took here, since we see
cases where on test machines a name resolution takes more than one second,
increase the minimal time to something higher to prevent such failures.

Also remove not used commented out code.

This test was failing randomly because it uses a timeout of 0.5 seconds, which
is sometimes not enough to run commands.

Increase the timeout to something large enough so that we don't have timeout
failures when test machine is busy.

Also simplify the whole thing by using python instead of parsing the output
of processes.

- from now on we want the reports as .xz
- fix type argument parsing which should make the promise effective now

See merge request !83

this was not html.

Also use os.path.join to manipulate paths

this program was comparing floats parsed from the report text and strings from
arguments passed on the command line, so basically it was not doing what was
intended.

because pt-query-digest are text files that can be large, we should except that
the users have compressed them.

This reverts commit 87b96e1b.

This reverts commit 099295af.

This reverts commit a0aa8b35.

but read only as much as we expect to receive. It should make tests more
stable

As python3 only accept binary types for sockets

Keep log file for debugging and use cleanup function to be sure
to correctly stop services

to simplify the code

See merge request !81

this should be used on testcase in future too, to always bootstrap with the same code-base.

This depends this be released first: slapos!747

   The generation of the link and the verification were inconsistent, this commit
   normalize both.

   PS.: Software Links are deprecated, it should be removed in future, as it lost
   the goals

While adding the support in "promise: Support ssl_certificate in
check_surykatka_json" coverage for error reporting was missing, which has been
extended in this fix.
