This feature can be used for unauthorized access to apis - e.g. for
reporting service if it is run on the same machine. Since now it becomes
recommended way for the interprocess communication, thus some options
(e.g. creating user with as-service flag) are no longer available now
The issue appears when there is no boto, jinja and some other libraries
are not installed because the classes which use these libraries are
still being imported inside the package file. The fix removes those
imports from package root, because they should not be here, in fact,
content of report and upload packages must be imported only inside the
trigger class and only if they are actually required
This commit also adds setuptools as required dependency since it is used
for some parsers (previously it was provided dependency)
this also requires to move default configuration files to share/ahriman.
Thus the following features have been added
* default configuration is not stored in /usr/share/ahriman/settings
* package installed via PKGBUILD now copies files from /usr
* configuration class now fallbacks to default in /usr
