* SMTP config: add global and local password file fields
Add config fields (for both global email config and route-specific email
config) that specify path to file containing SMTP password. We don't
want the password in the config file itself, and reading the password
from a k8s-secret-backed file keeps the password itself "encrypted at
rest" in etcd, and cleanly separated from the rest of the AM config.
I used the same approach as pull request #2534 "Add support to set the
Slack URL in the file"
<https://github.com/prometheus/alertmanager/pull/2534/files> in the
upstream repo.

* notify/email: wrap all errors for easier debugging
In addition, this commit passes the current context to the TCP dialer
and it doesn't log any QUIT errors if the email delivery wasn't
successful.

* Fix typo
Signed-off-by: Simon Pasquier <spasquie@redhat.com>
Instead of keeping all notifiers in the notify package, it splits them
into individual sub-packages. This improves readability and
maintainability of the code.
