sshpeer: add a configurable hint for the ssh error message

Adding a possibility to configure error hint to be shown in the case of problems with SSH. Example of such hint can be "Please see http://company/internalwiki/ssh.html".

Test Plan:
- Ran hg pull with broken link and verified the output has no hint by default:

```
pulling from ssh://brokenrepository.com//repo
remote: ssh: Could not resolve hostname brokenrepository.com: Name or service not known
abort: no suitable response from remote hg!
```

- Run hg pull --config ui.ssherrorhint="Please see http://company/internalwiki/ssh.html":

```
pulling from ssh://brokenrepository.com//repo
remote: ssh: Could not resolve hostname brokenrepository.com: Name or service not known
abort: no suitable response from remote hg!
(Please see http://company/internalwiki/ssh.html)
```
