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
move logic to separated shell scripts and also create shell script for
repository setup
Also force create directory according to systemd recommendations
* initial auth implementation
* add create user parser
* add tests
* update dependencies list
* add login annd logout to index also improve auth
* realworld fixes
* add method set_option to Configuration and also use it everywhere
* split CreateUser handler to additional read method
* check user duplicate on auth mapping read
* generate salt by using passlib instead of random.choice
* case-insensetive usernames
* update dependencies
* update configuration reference
* improve tests
* fix codefactor errors
* hide fields if authorization is enabled, but no auth supplied
* add settings object for auth provider
* readme update
