Update ORCA version

[danepowell]

Changes proposed

• Update ORCA to master
• Fix code style issues due to new coding standards
• Add caching dir to travis.yml according to ORCA release notes: https://github.com/acquia/orca/releases/tag/v1.1.0

Should have no functional impact, this is just improving ORCA integration and a follow up to Travis' PR here: #3882

@TravisCarden we need to figure out why ORCA is scanning markdown files as if they were PHP, I assume this is due to a recent change in ORCA or coding standards?

[TravisCarden]

Yes, @danepowell. Acquia Coding Standards recently fixed an issue in acquia/coding-standards-php#1 where a bug in PHPCS was preventing Coder Sniffer from checking various file types it means to, including Markdown. This is a case of "fixing ours broke yours". :)

But looking at your actual failures, you have a few "Expected 1 newline at end of file" that are valid. The only problem is docs/configuration-management.md, and I think Coder Sniffer is incorrectly trying to check it because it's finding a PHP open tag (<?php) in it. I believe that's a bug, and I've reported it at Sniffer incorrectly applies PHP rules to non-PHP files if they contain PHP tags [#3086639]. I've confirmed that you can get around it by using code blocks with syntax highlighting, like this:

    ```php
    $available_modules = system_rebuild_module_data();
    $dependencies = array();
    foreach ($available_modules as $name => $module) {
      if ($module->info['package'] == 'My Bundle') {
        $dependencies[] = $name;
      }
      \Drupal::service('module_installer')->install($dependencies);
    }
    ```

Thanks a lot for the investigation and help, it seems to be working now.
