.Synopsis
Installs the OMS agent on remote computers.
.DESCRIPTION
Either downloads the installer from a URL or copies the installer via the powershell session. Can detected if a previous version is installed and skip if so. If allready installed WorkSpaceId and WorkSpaceKey added to previous install. Doesn't detect invalid workspace IDs or Keys.
.EXAMPLE
Install-OmsAgent -sourcePath 'c:\MMASetup-AMD64.exe' -workspaceID '<workSpaceID>' -workspaceKey '<workSpaceKey>' -Verbose
.EXAMPLE
Install-OmsAgent -computerName <computerName> -workspaceID '<workSpaceID>' -workspaceKey '<workSpaceKey>' -Verbose
.EXAMPLE
$workSpace = Get-Credential
Install-OmsAgent -computerName 'computerOne' -workspace $workSpace -verbose
