On my self-hosted Windows runners, the `git`, `ssh-agent`, and `ssh-add`
commands are not located in the locations that are currently hard-coded
in `paths.js`.
With this PR, I am able to get this action to work on my runners as
follows:
```yaml
- uses: webfactory/ssh-agent@...
with:
ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}
git-cmd: git
ssh-agent-cmd: ssh-agent
ssh-add-cmd: ssh-add
```
This commit adds the new `log-public-key` action input.
Closes#122 (contains the suggested changes plus a few tweaks and documentation), fixes#100.

According to https://github.com/actions/runner/issues/987, this should run the post step (cleanup.js) also when a workflow fails.
Probably most important on self-hosted runners that are not ephemeral, to terminate SSH agents from failed jobs as well.
Thanks to @thommyhh for this contribution!
Unless the `SSH_AUTH_SOCK` is configured explicitly, this change will make the SSH agent use a random file name for the socket. That way, multiple, concurrent SSH agents can be used on non-ephemeral, self-hosted runners.
A new post-action step will automatically clean up the running agent at the end of a job.
Be aware of the possible security implications: Two jobs running on the same runner might be able to access each other's socket and thus access repositories and/or hosts.
