Add queryfilter package and ExpectResourceDisplayName query check

[SBGoods]

Related Issue

Fixes #565

Description

Adds a new queryfilter package and QueryFilter interface for implementing declarative logic for filtering query results before the results are passed as input for a QueryCheck. This could be used to apply a check to a certain subset of results or as a lookup mechanism to check a specific result.

Filters are implemented at the query check level, so a single test step can have multiple independent query checks with their own filtering.

The current implementations of query filters are:

• FilterByDisplayName
• FilterByResourceIdentity()

This PR also introduces a new ExpectResourceDisplayName() query check that takes a filter and knownvalue.stringcheck for the display name as input and asserts that the display name matches the input after filtering.

Rollback Plan

• If a change needs to be reverted, we will roll out an update to the code within 7 days.

Summarizing a chat @SBGoods + I had offline, all of the code looks good to me here, we just want to make sure that the solution here meshes with how AWS was viewing the original problems in #565 + #563. More discussions to happen offline 👍🏻

Thanks @SBGoods LGTM 💯

Before we release I think we should also remove the ContainsResourceWithName check since the ExpectResourceDisplayNameExact check now supersedes it.

Using a querycheck that uses a filter removes other results for all subsequent querychecks

Everything LGTM, I had one question about the new interface, but I don't have a major problem with it as-is 🚀
