cTentacleAgent add support for proxy servers

[thebrianlopez]

Team, Great job on this DSC Module !!! Go Octopus !

Use case:

• When tentacle is deployed to an environment where tentacle cannot directly communicate to the Octopus Server allow use of a proxy server.

Workaround:

• API already supports ProxyId property. As a workaround we manually perform a POST to the API:

$header = @{ "X-Octopus-ApiKey" = "API-xxx" }

$body = @{ 
      Endpoint = @{
        CommunicationStyle = "TentaclePassive"
        Uri = "$tentacleURL`:$tentaclePort/"
        Thumbprint = $TentacleThumbprint
        ProxyId = $proxyId
      }
      EnvironmentIDs = @($environmentIds)
      MachinePolicyId = $machinePolicyId
      TenantIds = @($tenantIds)
      TenantTags = @($tenantTags)
      Name = $tentacleName
      Roles = @($octopusRole)
      Status = "Unknown"
      IsDisabled = $false
    } | ConvertTo-Json -Depth 10

Invoke-RestMethod "$octopusServerUrl/api/machines" -headers $header -Method Post -Body $body

Hi @thebrianlopez, thanks for the suggestion!
At this point, we're unlikely to be able to tackle this in the near future, especially as you've got a workaround.
That said, we'll happily accept PRs to get functionality in. If you're interested, let me know and I can give you some pointers about how to tackle it.

I'm curious about what pointers you have :)
