Change GetComponentsParams "ProviderType" from "provider" to "type"

[mcarbonneaux]

This PR is to correct the issue #492 i've changed GetComponentsParams ProviderType from "provider" to "type".

cf: https://www.keycloak.org/docs-api/latest/rest-api/index.html#_component

i've not changed the attrribute name "ProviderType" just the params name ("type" in place of "provider") to avoid changing the rest of the code.
