Add "Name" ListOption for filtering list results

[sunny-b]

The Mongo Atlas API supports filtering list results based on a name parameter.

Link: https://docs.atlas.mongodb.com/reference/api/organization-get-all/#resource

It would be really useful to have this supported in the Go Client as well. At the moment, it looks like the only ListOptions that are supported are PageNum, and ItemsPerPage

go-client-mongodb-atlas/mongodbatlas/mongodbatlas.go

Lines 130 to 138 in a663e09

	// ListOptions specifies the optional parameters to List methods that
	// support pagination.
	type ListOptions struct {
	// For paginated result sets, page of results to retrieve.
	PageNum int `url:"pageNum,omitempty"`
	// For paginated result sets, the number of results to include per page.
	ItemsPerPage int `url:"itemsPerPage,omitempty"`
	}

We use Ops Manager at work and we depend on this feature in the API. We want to use this Go client but we would need this feature to be supported.

It is a pretty small change and I could easily make a PR for it. I've already made the change in my own fork:

Ah I see it might be better to create an OrganizationListOptions struct similar to ContainerListOptions

go-client-mongodb-atlas/mongodbatlas/containers.go

Lines 30 to 33 in d1f10b2

	type ContainersListOptions struct {
	ProviderName string `url:"providerName,omitempty"`
	ListOptions
	}

I'm closing this as it was fixed by #144
