Add support for dynamic content

[iamEAP]

Problem / motivation

We'd like the ability to search for, get details on, create, update, and delete dynamic content.

Proposed resolution

We should add support for dynamic content, as well as generic content sections. Potentially:

// Dynamic content.
$client->api('dynamicContent')->search($query, ['depth' => 'complete']);
$client->api('dynamicContent')->show($id);
$client->api('dynamicContent')->create($content);
$client->api('dynamicContent')->update($id, $content);
$client->api('dynamicContent')->delete($id);

// Content sections.
$client->api('contentSection')->search($query, ['depth' => 'complete']);
$client->api('contentSection')->show($id);
$client->api('contentSection')->create($content);
$client->api('contentSection')->update($id, $content);
$client->api('contentSection')->delete($id);

Details

• Content sections /api/REST/2.0/assets/contentSection[s | /[id]], documented [here].
• Dynamic content /api/REST/2.0/assets/dynamicContent[s | /[id]], which is undocumented.
