Adding automatic filters

[aaronparker]

I've created a working solution for adding output filters for Get-EvergreenApp. This should simplify returning details for a specific application by not requiring the use of Where-Object.

The filters can be added to /Evergreen/Filters, along side the cached Apps and Manifests. For example, adding /Evergreen/Filters/MicrosoftTeams.json with the following content:

{
    "filters": [
        {
            "property": "Release",
            "operator": "eq",
            "value": "Enterprise"
        },
        {
            "property": "Architecture",
            "operator": "in",
            "value": ["x64", "ARM64"]
        }
    ],
    "logicalOperator": "and"
}

Will automatically filter the output from `Get-EvergreenApp -Name "MicrosoftTeams":
