Follow symlinks when copying automation repositories

[paulbarfuss]

What does this PR do?

Allows resource-dispatcher to clone and copy repositories containing symlinks with shutil.copytree

How should this be tested?

The infra-ansible repository is an example of one that will fail at this step due to symlinks that will recurse to an infinite path.

repositories:
  - name: infra-ansible
    url: https://github.com/redhat-cop/infra-ansible.git
    ref: main

This seems to run immediately when the first task is received by the dispatcher and will cause the /tmp dir to recursively fill up with symlinks, for example:

$ ls -alh roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/roles/rhsm/tests/
