Performance telemetry collection for trending data

Here is a sample for using the module for performance measurements:

Import-Module "PSSnowball" -force
$results = @()

# Start run
# The PwshPath parameter is for testing a version of PowerShell other than the default installation.
Start-PSSnowballRun -Verbose -InstrumentationKey '<PerfAppInsightsKey>' -PwshPath '<PwshPath>'

# Make sure powershell analysis cache is setup
# Needed for testing PowerShell modules / cmdlets to account for Command Discovery and Auto loading.
Invoke-PSSnowballRunInitScript -ScriptBlock { Get-Module -ListAvailable } | Out-Null

# Get-Help test
$results += Invoke-PSSnowballTest -TestName "GetHelpNonExistent" -ScriptBlock { Get-Help DoesNotExist -ErrorAction SilentlyContinue} -Setup { $ProgressPreference = 'silentlycontinue'; $originalPath = $env:PSModulePath; $env:PSModulePath = (Join-Path $PSHOME "Modules")} -TearDown { $env:PSModulePath = $originalPath } -Verbose

# Get-Command test
$results += Invoke-PSSnowballTest -TestName "GetCommand" -ScriptBlock { Get-Command } -Setup { $originalPath = $env:PSModulePath; $env:PSModulePath = (Join-Path $PSHOME "Modules")} -TearDown { $env:PSModulePath = $originalPath } -Verbose

# Get-Module ListAvailable test
$results += Invoke-PSSnowballTest -TestName "GetModuleListAvailable" -ScriptBlock { Get-Module -ListAvailable } -Setup { $originalPath = $env:PSModulePath; $env:PSModulePath = (Join-Path $PSHOME "Modules")} -TearDown { $env:PSModulePath = $originalPath } -Verbose

# Stop run
Stop-PSSnowballRun

# Results
$results
