feat: SMTP Templates

[doncicuto]

With this feature you are able to choose an SMTP template and default settings are already made, so you only have to give my configuration specific settings.

In this PR there are default settings for Amazon SES, Mailgun, Mailjet, Postmark, Sendgrid and a Generic SMTP provider. If you have known settings for other providers let me known and I'll add them during this review.

This is a video showing this feature:

This PR has many frontend/backend changes, some of them are breaking changes:

• As we now are able to have many SMTP configurations an id must be used to specify the config to be updated, removed, activated or deactivated or if you want to change SMTP password. Also we must activate a provider in order to send emails.
• golangci-lint contextcheck complained about passing context to InstanceAggregateFromWriteModel.
• I've kept UpdateSMTPConfigPassword in API but when you create or edit an SMTP config you can send a password.
• GetSMTPConfig API will give us the current ACTIVE configuration.

I've done my best, but I guess that many things will be wrong in backend as I'm still trying to learn more about it. I thank you in advance for your review

@doncicuto I had another look, I think they are small chances that I missed but would be a good idea. Could you have a look if the comments are clear for you?

[doncicuto]

No, thank you and specially to the whole team reviewing this issue. I hope that things work fine and my code can be fixed and improved during this review

Resolved

Thank you，How is Office365 configured?

[doncicuto]

Hi @Beatirce, unfortunately I couldn't add a template for Office/Microsoft365 as I have no account to test against it. I created a PR on friday to add an outlook.com template and a fix that should allow login auth for smtp communication with that provider, but I've no way to test against Office365. I'm on Discord so if you or anybody interested in this feature want to contact me and provide an account to test I'd love to try (I'm not sure if Oauth with SMTP will be needed).
