fix: externalise structure for query and path params

[wtrocki]

Description

Create separate structure for query params

Long

As part of the migration, I see recurrent theme where GET url arguments are returned as part of the Fluent API. E.g

 s.clientv2.PerformanceAdvisorApi.
        ListSuggestedIndexes(s.ctx, projectID, processName).
        NExamples(1) // This is query param
        Execute()       

Due to the architecture in the CLI (stores) we see need to pass those arguments to functions This usually means:

• Passing from 3 to 10 arguments to methods
• Create some intermediate objects in the CLI

Manual SDKs have been supporting this by GET arguments being represented as struct: https://github.com/mongodb/go-client-mongodb-atlas/blob/437d9b43222e10c0fd565d979eafd85f80c199e2/mongodbatlas/performance_advisor.go#L105-L130

This PR brings parity (with level of backwards compatibility between both SDKs.
