[PowerShell] Deploy-FinOpsHub – Local template file

📝 Scenario

As a hub admin, I need to deploy a hub from a local template in order to deploy my customized template

💎 Solution

Update Deploy-FinOpsHub command to support deploying a local template.

Synopsis stays the same. Initialization will happen automatically, so there are no new parameters.

Syntax

Deploy-FinOpsHub `
    ... `
    [-TemplateFile <string>]

Description

The Deploy-FinOpsHub command creates a new FinOps hub instance. If the -TemplateFile parameter is specified, that is the template that is used; otherwise, the FinOps hub template is downloaded from GitHub using the specified version.

FinOps hubs has certain prerequisites that must be met before the template can be deployed. The Deploy-FinOpsHub command will internally call Initialize-FinOpsHubDeployment to validate and apply these requirements. Initialization must be done by a subscription contributor due to resource provider registration. Resource group contributors can execute the Deploy-FinOpsHub command but it will fail if these requirements are not met. Note initialization does not account for any custom requirements when -TemplateFile is specified.

We could use your help:

1. Please vote this issue up (👍) to prioritize it.
2. Leave comments to help us solidify the vision.

Start by locating the Deploy-FinOpsHub command and its existing template-download path, then inspect how it invokes Initialize-FinOpsHubDeployment. Implement support for the optional -TemplateFile path while preserving the GitHub download behavior when it is omitted, and verify both paths with the repository's existing tests or command validation.
