Allow beakerlib library without url/path

[LecrisUT]

Without those keys we take the tmt tree to be the default value for the path

Ok @HouMinXi ready for a second try. To elaborate on the requirement. Let's say you have a repo example.com/Me/some_repo that has both beakerlib library and some tmt tests that want to test that library, something arranged like:

$ tree -a .
.
├── .fmf
│   └── version
├── my_lib
│   ├── lib.sh
│   └── main.fmf
├── plans
│   └── main.fmf
└── tests
    ├── my_lib.fmf
    └── test.sh

5 directories, 6 files

Then what you care about is how you define the tests, e.g. in this case it is /tests/my_lib

summary: Test the my_lib beakerlib library
test: test.sh
require:
  - type: library
    name: /my_lib
    nick: some_repo

and the tests file

#!/bin/bash
. /usr/share/beakerlib/beakerlib.sh || exit 1

rlJournalStart
    rlPhaseStartSetup
        rlRun "rlImport some_repo/my_lib"
    rlPhaseEnd

    rlPhaseStartTest
        rlRun "..."
    rlPhaseEnd

    rlPhaseStartCleanup
    rlPhaseEnd
rlJournalEnd

Particularly see the some_repo here matching nick and should match however you or your external users would consume the beakerlib library.

Hope this breakdown makes sense?

Here is my test topo
repo: https://gitlab.cee.redhat.com/mhou/kernel
branch: mhou_tmp_branch

My simplified file-topology is as follows:

.
├── .fmf
│   └── version
networking
├── common
│   └── main.fmf
└── openvswitch
    └── topo
        └── main.fmf

in /networking/openvswitch/topo/main.fmf, I define the local file library as below:

summary: ovs topo testing
description: |
    FIXME: more description about ovs topo
contact: Rick Alongi <ralongi@redhat.com>
component:
  - openvswitch
test: bash ./runtest.sh
framework: beakerlib
require:
  - type: library
    name: /networking/common
    nick: kernel
duration: 24h
extra-summary: /kernel/networking/openvswitch/topo
extra-task: /kernel/networking/openvswitch/topo

In plan-level I define discover as below:

- name: ovs_topo
      how: fmf
      url: https://gitlab.cee.redhat.com/mhou/kernel/-/archive/mhou_tmp_branch/kernel-mhou_tmp_branch.tar.gz
      url-content-type: archive
      path: kernel-mhou_tmp_branch
      test:
        - ^/networking/openvswitch/topo$

run the tmt with debug mode, raise error Failed to find library kernel/common at /var/tmp/tmt/run-008/openvswitch/topo/plan/discover/ovs_topo/tests
