Externalize TLS version on Quota's mailing

[GutoVeronezi]

Description

Some servers (like microsoft) are deprecating TLSv1 and TLSv1.1.

On Quota's mailing settings, ACS uses the protocol TLSv1; therefore, operators do not have options to choose which version they want to use.

This PR intends to externalize the protocol setting on Quota's mailing.

How Has This Been Tested?

It has been tested locally on a test lab.

1. I had Enabled Quota's plugin on the management server and configured it to use Gmail's SMTP server.

server address: smtp.gmail.com
username: gmail address
password: gmail password
port (TLS): 587

2. On Quota - All Accounts, I added 10 credits to my user and set 20 as min balance.

3. I had added an gmail address to Accounts > <account> > Users - Email.

4. I allowed Less secure app access on my Google account.

5. I had restarted management server.

6. And I called quota update API via Cloudmonkey.

7. In Gmail, we have an option to show original message, which provides the TLS version and the cipher. So I changed the configuration some times and sent some alerts to verify if both versions, in configuration and gmail, are the same.
