Ability to choose smtp identifier in email enrollment event

[brunocascio]

Is your feature request related to a problem? Please describe.

We need to set SMTP config per realm due we use multiple brands and we don't want to use the same for example, SMTP sender.

Describe the solution you'd like

Add a field in the event framework to override the global configuration from privacyidea config 'email.identifier'

Alternative solution

Use additional_params field?

Additional context
We're using keycloak as a centralized solution for authentication. We have 2 clients (foo.com and bar.com)
Each client want to send email with their smtp configuration.

Gahh! You want to use email tokens? Evil! Very specific.
And you think you need to autoenroll these tokens to the users?

The options of the tokenhandler are defined here:
https://github.com/privacyidea/privacyidea/blob/master/privacyidea/lib/eventhandler/tokenhandler.py#L169

So you could add something like this:

"smtp_server": {
                            "type": "bool",
                            "visibleIf": "tokentype",
                            "visibleValue": "sms",
                            "description": _("The server which will be used to send email-tokens."),
                            "value": smtp_server_list
                        },

You could get the "smtp_server_list" from lib/smtpserver.py:get_smtpservers().

I just made a fairly naive implementation for this feature. If there is any feedback it'd be appreciated :)

Hey folks @cornelinux @Jameru,

I think @Jameru's pull request works pretty well for the feature requested.

I'm glad to collaborate if needed 🙌
