AzureDevOpsDsc: Common module should be built with ModuleBuilder

[johlju]

In the source/Modules/AzureDevopsDsc.Common should be built using the pattern public/private folders.

We ought to be able to build the PSM1 by merging the Public/Private/Classes/etc. folders the same way as the top module.
We should configure the NestedModules section in the build.yml

NestedModule:
  DscResource.Common:
    CopyOnly: true
    Path: ./output/RequiredModules/DscResource.Common
    AddToManifest: false
    Exclude: PSGetModuleInfo.xml
  AzDevOpsProject.Common:
    CopyOnly: false
    Path: ./source/Modules/AzureDevOpsDsc.Common
    AddToManifest: false

And remove the entry Modules from here:

AzureDevOpsDsc/build.yaml

Lines 5 to 9 in 8d43d12

	CopyPaths:
	- Classes
	- en-US
	- Examples
	- Modules

That will replace the dot-source code in the file below, and will speed up the usage of the distributed resources.

AzureDevOpsDsc/source/Modules/AzureDevOpsDsc.Common/AzureDevOpsDsc.Common.psm1

Lines 10 to 45 in 8d43d12

	# Resources

	"$PSScriptRoot\Resources\Functions\Private",
	# Server
	# Services
	"$PSScriptRoot\Services\Functions\Public"
	)
	$functions = Get-ChildItem -Path $functionSubDirectoryPaths -Recurse -Include "*.ps1"
	# Loop through all PSModule functions and import/dot-source them (and export them if 'Public')
	foreach ($function in $functions)
	{
	Write-Verbose "Dot-sourcing '$($function.FullName)'..."
	. (
	[ScriptBlock]::Create(
	[Io.File]::ReadAllText($($function.FullName))
	)
	)
	if ($function.FullName -ilike "$PSScriptRoot\*\Functions\Public\*")
	{
	Write-Verbose "Exporting '$($function.BaseName)'..."
	Export-ModuleMember -Function $($function.BaseName)
	}
	}
