Do not pass full apache context to vhost templates.

The full apache context variable can grow quite large if using multiple
vhosts with SSL certificates.
With 200 sites the apache variable is being rendered 200 times which resuls
in observed renderer output of about 950MB...

state.apply will result with MemoryErrors in such cases.

This PR modifies the templating code to _only_ use a per site context
and pass a trimmed down copy of the apache context instead of the full.

Drive-By: Correct indentation for context variables.
Drive-By: Remove duplicate map/apache functionality. Only use map.

# [1.1.0](https://github.com/saltstack-formulas/apache-formula/compare/v1.0.5...v1.1.0) (2020-10-14)

### Bug Fixes

* **ssl.conf:** fix pillar keys for SSLStapling in ssl.conf on debian ([65043f8](65043f8a61))

### Code Refactoring

### Features

* **ssl.conf:** add SSLSessionTickets to ssl.conf on debian ([41a7a83](41a7a83af0))

Refactor ssl.conf for debian

refactor(vhosts): reduce empty lines in standard.tmpl and proxy.tmpl

## [1.0.5](https://github.com/saltstack-formulas/apache-formula/compare/v1.0.4...v1.0.5) (2020-10-14)

### Bug Fixes

fix(package): avoid unnecessary state change

## [1.0.4](https://github.com/saltstack-formulas/apache-formula/compare/v1.0.3...v1.0.4) (2020-10-14)

### Bug Fixes

* **debian:** don't execute a2enmod on every run ([5844322](5844322de4))
* **debian:** fix default moddir on debian ([c17601e](c17601ee42))
* **logs:** don't change owners of logfiles with salt ([382e053](382e053c58))
* **vhosts:** replace %O with %b in default LogFormat ([2b52e11](2b52e11a8a))

### Tests

* **pillar:** remove modules that aren't installed from being enabled ([47ec5fc](47ec5fcc34))

Fix modules enable

fix(logs): don't change owners of logfiles with salt

The logs are created by apache or logrotate, but salt shouldn't change
permissions of existing logfiles everytime it runs.

%O needs mod_logio, which isn't enabled by default everywhere, so it
also shouldn't be used as default fallback LogFormat.
