<div class="block">Represents a storage plugin, defined by a (name, config) pair. The config
implies a connector definition, including a way to create the plugin
instance (<code>StoragePlugin</code>. Storage plugins are created lazily to avoid
long Drillbit start times. Plugin creation is synchronized as is closing.
<p>
A handle has a type used to determine which operations are allowed on
the handle. For example, inrinsic (system) plugins cannot be deleted or
disabled.
<h4>Caveats</h4>
Note that race conditions are still possible:
<ul>
<li>User 1 submits a query that refers to plugin p. The registry creates
an instance of plugin p and returns it. The planner proceeds to use it.</li>
<li>User 2 disables p, causing its entry to be updated in persistent storage
(but not yet in this entry)</li>
<li>User 3 submits a query that refers to plugin p. The registry notices that
the plugin is now disabled, removes it from the plugin list and closes the
plugin.</li>
<li>User 1 suffers a failure when the planner references the now-closed
plugin p.</li>
</ul>
This issue has existed for some time and cannot be fixed here. The right
solution is to introduce a reference count: each query which uses the plugin
should hold a reference count until the completion of the plan or fragment.
If we implement such a reference count, this is the place to maintain the count,
and to close the plugin when the count goes to zero.</div>
