Add filters/search for the Product Inventory

[mjherzog]

When working with hundred of Inventory Items you need the capability to search and filter by Item name.
Some common use cases are:

• Search/filter by package type
• Search/filter by package or component name.

Enhancement suggestion noted. As a short-term workaround, please note that you can use the text search feature of your browser to look for a package.

Of course, but that is very primitive and does not allow you to create a subset of data to work with.

@mjherzog Inventory tab search was added along in #3 PR #24

You can now use it to search the following fields:

• component__name
• component__version
• package__filename
• package__type
• package__namespace
• package__name
• package__version
• license_expression
• notes
• extra_attribution_text
• feature
• issue_ref

This should cover the basics but we can keep this issue opened for improvements regarding the Ui and active filters.
