Add additional Query error handling

[drew-russell]

Describe the solution you'd like

We should add additional error handling to the query base function.

1. If operation_name is populated, make sure it's at the start of the query
2. If variables are provided, make sure they are in the query
3. Potentially automatically remove "query" from the first part of the provided query body since its not needed

import rubrik_cdm

rubrik = rubrik_cdm.Connect()

operation_name = "ClusterDetails"

query = """
ClusterDetails($clusterID: String!) {
  cluster(id: $clusterID) {
    version
  }
}
"""

variables = {
    "clusterID": "me"
}

cluster_details = rubrik.query(query, operation_name, variables)
