Optional TLS/Authentication for Contact Support Menu

[dmccoystephenson]

Problem

In the event that an email server does not support TLS or authentication, the Contact Support Menu ceases to function.

Solution

TLS and authentication have been made optional via the introduction of the CSM_TLS_ENABLED and CSM_AUTH_ENABLED environment variables.

Testing

• Unit tests have been added and verified to be passing.
• Sending an email through Google's email server has been verified to work with TLS / AUTH enabled.
• Sending an email to a locally-running mail server has been verified to work with TLS / AUTH disabled.
• Sending an email through WYDOT's mail server has been verified to work with TLS / AUTH disabled.

Note

It should be noted that if pretty formatting is enabled, WYDOT's email server won't accept & forward the email. Pretty formatting is explicitly disabled in the contact support menu due to this.

Just the one question, otherwise looks good!

Keeping this as a draft for now until I can re-verify the functionality for this PR
