[WIP] Add scripts to fetch and analyze Kubernetes pod and node data

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Following the same get/analyze pattern and common parareters used in other azure/ scripts, createa 2 python scripts to: 1)

fetch pod information from KubePodInventory using az 'rest' and KQL
fetch node information from KubeNodeInventory using az rest and KQL
allow filtering by namespace and time range

An analysis script that takes the csv output(s) created by (1), and:
works out which pods belong to which HPCC components
cross-reference the pods -> computer(nodes)
workout how many pods/nodes each component consumed for how long
