Support for creating new Event Logs

[craig-martin]

Would be great if I could use this resource to create new event logs and event sources.
For example today I would call New-EventLog like this to get this done:

### Create log and source
New-EventLog -LogName BigLog -Source TheHorsesMouth

My lame workaround is to use the Script resource:

Script MyEventLog
{
    GetScript  = {
        return @{LogName='MyEventLog'}
    }
    TestScript = {
        try{
            Write-Verbose "Getting EventLog 'MyEventLog' with Source 'MySource'"
            Get-EventLog -LogName MyEventLog -Source MySource -Newest 1 | Out-Null
            return $true
        }
        catch{
            Write-Warning 'Log not found'
            return $false
        }
    }
    SetScript  = {
        Write-Verbose "Creating EventLog 'MyEventLog' with Source 'MySource'"
        New-EventLog -LogName MyEventLog -Source MySource -Verbose
    }
}

I'd also like this to be implemented.

I've ran into this problem as well and I'm working on a PR to add it.

While looking at using this as a basic layout for implementing it I've discovered a small problem:

• The test block runs and find that the LogName doesn't exist (or it's sources don't match)
• The set block runs and creates the LogName with the various sources specified
• The test block runs again and can't find the LogName because it doesn't have any log entries in it.

So my current solution is that as part of the Set block it will write a log entry for each Source defined. This will populate the log to actually create it but also populate the Source entries allowing further Test blocks to run correctly.

Does anyone see any issues with this? Other than having a few spurious event log entries that might flag in monitoring solutions.

Submitted PR #14 which adds this functionality.
