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

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.

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

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

   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.

This is another fixup for commit
1c8269b2.

This will lead to minimise amount of entries, and they will be only shown
when the status would change.

Improvements:

 * total_seconds from surykatka is parsed
 * failure-amount is configurable
 * various smaller bugfixes

/reviewed-on nexedi/slapos.toolbox!77

Result of the promise is not important for instantiation.

Sites with bad certificates are reported with null values in surykatka
output, thus they have to be handled correctly.

It means that the server didn't reply at all.

Show URL only once and having this in mind simplify messages still keeping
all information.

It is only checked when maximum-elapsed-time is passed and surykatka is
recent enough to report total_seconds.

Also improve reporting even more to provide readable information for those
massive promises with ERROR/OK mixed states.

Prefix with ERROR and OK messages for problems and ok checks, as they are
grouped together in the output.

This is another fixup for commit
1c8269b2.

This is not covered by tests since they use a fake_send method.
