Create uninstallation methods.

Analyse what each method exactly does, and undo the actions.

(Try to cluster the impact of the installation to the highest common denominator, e.g. the creation of the pki folder and the certificate generation in the /pki folder, which are done in two separate methods, can be undone by a single deletion of the pki folder.)

Review the installation methods and trace each action they perform, starting from the installer entry point. Define the corresponding cleanup actions, grouping related effects such as the pki directory and generated certificates; done means the installer’s changes can be reversed without leaving those artifacts behind.
