Disable TLS session tickets in Apache (#7771)
Fixes #7350.

This PR changes the parsed modules from a `set` to a `dict`, with the filepath argument as the value. Accordingly, after calling `enable_mod` to enable `ssl_module`, modules now need to be re-parsed, so call `reset_modules`.

* Add mechanism for selecting apache config file, based on work done in #7191.

* Check OpenSSL version

* Remove os imports

* debian override still needs os

* Reformat remaining apache tests with modules dict syntax

* Clean up more apache tests

* Switch from property to method for openssl and add tests for coverage.

* Sometimes the dict location will be None in which case we should in fact return None

* warn thoroughly and consistently in openssl_version function

* update tests for new warnings

* read file as bytes, and factor out the open for testing

* normalize ssl_module_location path to account for being relative to server root

* Use byte literals in a python 2 and 3 compatible way

* string does need to be a literal

* patch builtins open

* add debug, remove space

* Add test to check if OpenSSL detection is working on different systems

* fix relative test location for cwd

* put </IfModule> on its own line in test case

* Revert test file to status in master.

* Call augeas load before reparsing modules to pick up the changes

* fix grep, tail, and mod_ssl location on centos

* strip the trailing whitespace from fedora

* just use LooseVersion in test

* call apache2ctl on debian systems

* Use sudo for apache2ctl command

* add check to make sure we're getting a version

* Add boolean so we don't warn on debian/ubuntu before trying to enable mod_ssl

* Reduce warnings while testing by setting mock _openssl_version.

* Make sure we're not throwing away any unwritten changes to the config

* test last warning case for coverage

* text changes for clarity
