This is a sort of rollback to the pre #93c158b05 state with
several improvements.

For now, the nodeids calculation by ipa-run-tests is not stable,
since it depends on current working directory. Nodeids (tests
addresses) are utilized by the other plugins, for example.

Unfortunately, the `pytest_load_initial_conftests` hook doesn't
correctly work with pytest internal paths, since it is called
after the calculation of rootdir was performed, for example.

Eventually, it's simpler to follow the default convention for
Python test discovery.

There is at least one drawback of new "old" implementation.
The ignore rules don't support globs, because pytest 4.3.0+
has the same facility via `--ignore-glob`:

> Add the `--ignore-glob` parameter to exclude test-modules with
> Unix shell-style wildcards. Add the collect_ignore_glob for
> conftest.py to exclude test-modules with Unix shell-style
> wildcards.

Upon switching to pytest4 it will be possible to utilize this.
Anyway, tests for checking current basic facilities of
ipa-run-tests were added.

Completely remove ipaserver/install/ntpinstance.py

This is no longer needed as chrony client configuration
is now handled in ipa-client-install.

Part of ipclient/install/client.py related to ntp configuration
has been refactored a bit to not lookup for srv records
and/or run chrony if not necessary.

Automake manual section 13 What Gets Cleaned says that make maintainer-clean
should not remove files necessary for subsequent runs of ./configure.

It practically means that all usage of MAINTAINERCLEANFILES were incorrect
so I've removed them.

At the time of this writting
https://fedoraproject.org/wiki/Packaging:Guidelines#Manpages
says this:
  When installing man pages, note that they should be installed uncompressed
  as the build system will compress them as needed. The compression method
  may change, so it is important to reference the pages in the %files section
  with a pattern that takes this into account:
  %{_mandir}/man1/foo.1*

Removing the compression also allows to remove several install-data-hook
targets from Makefile.am files.

By default automake does not distribute man pages. This marks then with
dist_ prefix to force their distribution in tarball.
