Add a page for importing Metatag configurations

I just used the export link in the metatag UI (after editing the metatags). It gives me a window with something as I've shown below. I was assuming I'd have to copy and paste it into a file and then import it on my other sites.

$config = new stdClass();
$config->disabled = FALSE; /* Edit this to true to make a default config disabled initially */
$config->api_version = 1;
$config->instance = 'global:frontpage';
$config->config = array(
'title' => array(
'value' => '[site:name]',
),
'description' => array(
'value' => 'My description text blah blah.',
),
'keywords' => array(
'value' => 'fred, john, may',
),
'news_keywords' => array(
'value' => 'fred, john, may',
),
'canonical' => array(
'value' => '[site:url]',
),
'shortlink' => array(
'value' => '[site:url]',
),
);

Ah! To date I've mainly managed to backup and restore my database as the production site has no user modified content. But that is now changing and I won't be able to get away with that any more (except going in reverse, production to development, of course). I've exported/imported views and I've looked at features and patterns which seem to do what I need in some areas.

In the end I've gone for the deploy and configuration management modules (the latter because it seems to be the way D8 is going). However, I'd only set a specific metatag for the front page yet it didn't seem to transfer; I had to set a global metatag for it to transfer.
