Add deployment freeze override flags

[bec-callow-oct]

Background

[SC-96959]

Deployment freeze overrides for Octopus Server API were implemented in this PR, but there is currently no way to override a deployment freeze via the CLI.

This PR adds two new flags to the deploy release command. If deploying while a deployment freeze is active, both of these flags are required:
deployment-freeze-names and deployment-freeze-override-reason

Results

Before

$ ./octopus release deploy --project "Freeze test" --version 0.0.2 --environment Dev

Automation Command: octopus release deploy --project 'Freeze test' --version '0.0.2' --environment 'Dev' --no-prompt
Octopus API error: There was a problem with your request. [The environment Dev is frozen by freeze 1.]

After

When a deployment freeze exists

$ ./octopus release deploy --project "Freeze test" --version 0.0.2 --environment Dev --deployment-freeze-names "freeze 1" --deployment-freeze-override-reason "testing"

Automation Command: octopus release deploy --project 'Freeze test' --version '0.0.2' --environment 'Dev' --deployment-freeze-names 'freeze 1' --deployment-freeze-override-reason 'testing' --no-prompt
Successfully started 1 deployment(s)

When the deployment freeze is not found

$ ./octopus release deploy --project "Freeze test" --version 0.0.2 --environment Dev --deployment-freeze-names "fake freeze" --deployment-freeze-override-reason "testing"

Automation Command: octopus release deploy --project 'Freeze test' --version '0.0.2' --environment 'Dev' --deployment-freeze-names 'fake freeze' --deployment-freeze-override-reason 'testing' --no-prompt
Octopus API error: There was a problem with your request. [Unable to override freezes, no valid freezes were specified]

this should probably be singular, each instance of the parameter is single freeze name, which can be specified multiple times.

Suggested change

	FlagDeploymentFreezeNames = "deployment-freeze-names"
	FlagDeploymentFreezeName = "deployment-freeze-name"

Yes, good catch
