    Method createPromise in slapos.librecipe

    This method create a promise script which should return 0 whether the
    promise was kept.

In the same time, it is useless to define to logformat when only
one is used. Using format closer to default apache allows to
more easily use various log parsers

For performance analysis, it is mandatory to keep logs for a very long
time. Also it is sometimes required to analyse a bug that happened
more than one more ago, so we have no other choices than keep logs
and not remove them.
