Should we also include the platinum plan? (standard is deprecated)

Should we also include the platinum plan? (standard is deprecated)

I'm not sure.. would like to get some thoughts about it.

The reason I didn't include it is because databases offers a 'standard' plan which can be of isolated or shared database. For example, you can choose between isolated (the user selects host flavor) or shared (all parameters can be set by the user) for postgres or elasticsearch. This is the 'standard' or the 'default' plan. For Elasticsearch, the 'default' plan is the enterprise plan, but ES also has another plan called platinum plan. In the platinum plan, the users can only select isolated database. This isolated database was not implemented when infracost support for postgres was added.. So I am not sure if this is something new or something i'll have to implement as well.

Support for the platinum plan will need to be added. https://registry.terraform.io/providers/IBM-Cloud/ibm/latest/docs/resources/database#sample-elasticsearch-platinum-instance
