Add policy in Azure DevOps CLI extension

[gauravsaralMs]

Creating this task to evaluate inclusion of Policy in Azure DevOps extension

[gauravsaralMs]

Action	Present in VSTeam powershell module?	Should we have it in CLI? (proposal)
List Team Policy Type	Get-VSTeamPolicyType	Yes
Get Team Policy Type	Get-VSTeamPolicyType	Yes
Create policy	Add-VSTeamPolicy	Yes
Remove policy	Remove-VSTeamPolicy	Yes
Update policy	Update-VSTeamPolicy	Yes
Get policy	Get-VSTeamPolicy	Yes
List policy	Get-VSTeamPolicy	Yes
List policy Evaluation	No	Yes
Get policy Evaluation	No	Yes
Requeue policy Evaluation	No	Yes

Recommendation:
In order to make policy really useful we need to give a end to end story that is why evaluation looks like a set which we should have

Proposal:

Action	Command	Parameters	Response

List policy	Az devops policy list	Org, Project,	Direct response from API
List policy Evaluation	Az devops policy evaluation list	Org, Project, Artifact Id (string), includeNotApplicable (yes/ no), top (int), skip (int)	Direct response from API
Get policy Evaluation	Az devops policy evaluation get	Org, Project, Evaluation Id	Direct response from API
Requeue policy Evaluation	Az devops policy evaluation requeue	Org, Project, Evaluation Id	Direct response from API

We will need to close on how can we expose settings to CLI user
Option 1:
Just take string as input (user will have to pass a json serialized string)

Option 2:
Split policy create in multiple create which are type specific, then also we will not be able to expose complete settings capability because for
Same policy type setting can differ like JArray in scope
