Misconfigured search in containers and containertemplates plugins

[mikkonie]

Describe the bug
Search is misconfigured in the containers and containertemplates project app plugins. search_enable is set to True, but the search() method has not been implemented and the search results template is missing.

This results in the default search() method implementation being called and the Title to be displayed label being visible in the search results view. See screenshot below.

To Reproduce
Steps to reproduce the behavior:

1. Search for any string
2. Look at the search results

Expected behavior
Search should be implemented to search for relevant content and display the results, or disabled by setting search_enable=False.
