[RFE] Allow running providers selectively in analyzer addon

[pranavgaikwad]

Problem

We are anticipating changes in the analyzer-lsp base image. We will split up providers into their individual images. In the enhancement, we mainly want to discuss:

• How exactly we will run the addon Pod with user selected language providers? An important problem here is sharing the source location.
• How will the UI filter targets/rulesets appropriate for provider(s) that will be selected.
• How could someone use their own provider image? This is not just overriding an existing provider image, but can we make it so that users can also test with new language providers that are not yet in the UI?
• How can we be sure that provider containers be terminated when the addon has completed?
• How will credentials be injected into provider containers? Example: maven settings file.
• In future, we might need to run .NET on a windows host remotely.

Solution

See: Hub Issue for hub/addon details.

Filtering/Selection

Targets will be filtered and Providers will be selected by Language tag(s). This will likely depend on the Application Discovery feature.

Addon Extensions

An Addon Extension is primarily an optional container definition along with criteria defined by a new CR. Providers will be defined to the hub as an Addon Extension. The first supported selection criteria will be by application tag matching.

Task Pod

The task pod will be configured with a main container for the addon and a sidecar container for each of the providers. All containers will mount an EmptyDir volume into /shared for sharing files such as credentials and source code trees.

Custom Providers

Users may define new providers for testing using the UI by added a new Extension CR that is mapped to a new Language tag. Then, add/replace the language tag so that extension (provider) is selected.

Testing with the API is simpler. The user would add the Extension, and submit an analysis tag using the API that references the extension explicitly.
