I am making this change since Microsoft, Google, and Apple have all chosen to deprecate TLS 1.0 and TLS 1.1 in early 2020. In late 2018, the companies recorded that less than 1.4 percent (max) of their connections used < TLS 1.2.
Output before change:
```
docker run --rm -ti -p 3333:3333 drwetter/testssl.sh https://host.docker.internal:3333
Testing protocols via sockets except NPN+ALPN
SSLv2 not offered (OK)
SSLv3 not offered (OK)
TLS 1 offered (deprecated)
TLS 1.1 offered (deprecated)
TLS 1.2 offered (OK)
TLS 1.3 offered (OK): final
NPN/SPDY h2, http/1.1 (advertised)
ALPN/HTTP2 h2, http/1.1 (offered)
```
Output after change:
```
docker run --rm -ti -p 3333:3333 drwetter/testssl.sh https://host.docker.internal:3333
Testing protocols via sockets except NPN+ALPN
SSLv2 not offered (OK)
SSLv3 not offered (OK)
TLS 1 not offered
TLS 1.1 not offered
TLS 1.2 offered (OK)
TLS 1.3 offered (OK): final

* Refactoring servers to support custom workers and graceful shutdown.
* Refactoring workers to support custom mailers.
* Refactoring mailer to be an interface, with proper instances instead of a single global instance
* Cleaning up a few things. Locking maillogs for campaigns set to launch immediately to prevent a race condition.
* Cleaning up API middleware to be simpler
* Moving template parameters to separate struct
* Changed LoadConfig to return config object
* Cleaned up some error handling, removing uninitialized global error in models package
* Changed static file serving to use the unindexed package
Added the modified_date field to results so it's easy to keep track of the last results that were modified without having to parse every event. Updated the tests to reflect the changes.
Adds the capability to report phishing campaigns using an email client extension.
**Note: Gophish does not currently provide an email client extension out of the box. This is simply a mechanism to let existing email client add-ons send report status information to Gophish, and have that information reflected in the dashboard.**
