`pungi-gather` (the tool that underlies both the `pkgset` and `gather`
phases) contains profiling code that will log statistics about how long
different function calls take. However, pungi-koji did not contain a
way to pass the ``--profiler`` argument to enable this.
This change adds a new configuration option ``gather_profiler`` which,
when set to true, simply passes the argument to `pungi-koji`. Hopefully
this can help shed some light on what is happening in some of our
longer-running composes.

Pungi write image config file with name of <format>-<name>.cfg, if there
are two or more image configs present for different arches under the same
variant and with same format & name, the config file can be overwritten,
and result in invalid image conf file.
Example:
image_build = {
'^Server$': [
{
'image-build': {
'format': [('qcow2', 'qcow2'),],
'name': 'fedora-guest-image',
'target': 'guest-fedora-26-image',
'version': '26',
'ksurl': "git://git.example.com/ks.git?fedora#HEAD",
'kickstart': "fedora-26-kvm.ks",
'ksversion': 'f26',
'distro': 'fedora-26',
'disk-size': '10',
'arches': ['x86_64'],
'repo': ["http://example.com/linux/fedora/26/Everything/x86_64/os", ]
}
},
{
'image-build': {
'format': [('qcow2', 'qcow2'),],
'name': 'fedora-guest-image',
'target': 'guest-fedora-26-image',
'version': '26',
'ksurl': "git://git.example.com/ks.git?fedora#HEAD",
'kickstart': "fedora-26-kvm.ks",
'ksversion': 'f26',
'distro': 'fedora-26',
'disk-size': '10',
'arches': ['ppc64le'],
}
},
],
}
In this case, config file "qcow2_guest-fedora-26-image.cfg" will be
created for both x86_64 and ppc64le under the same variant dir, and
there is a high chance it will be over-written while Pungi creating the
koji task. We can add arch name(s) in config filename to avoid that.
