Get plan for prerelease version for individual modules

[johlju]

I would like to see that it would be possible to specify that Get-ModuleFastPlan should fetch the latest prerelease version for an individual module.

@('Pester', @{ModuleName='DnsServerDsc';Prerelease = $true}) | Get-ModuleFastPlan -Update

which would result in (latest version as of today):

• DnsServerDsc v3.0.1-preview0002
• Pester 5.5.0

Passing PreRelease to the command Get-ModuleFastPlan does not seem to have any effect of fetching latest preview version either.

Since modulespecification has no native support for this, I've decided to use the syntax of adding a ! to either the beginning or end of the modulename. While ! is a valid filename character, it is not a valid nuget package character, and thus a module with this name would not be published to an nuget gallery. I'm OK with the edge case that this maybe would work with a filesystem package, and I'm going to put that into unsupported territory.

I will probably add that Prelease property you suggested for the hashtable cast syntax as well.

Usages

Install-ModuleFast 'Az!'  -WhatIf
@('Pester', @{ModuleName='DnsServerDsc';Prerelease = $true}) | Install-ModuleFast -WhatIf
@('Pester', @{ModuleName='!DnsServerDsc'}) | Install-ModuleFast -WhatIf
Install-ModuleFast 'PrereleaseTest!<0.0.2' -WhatIf

EDIT: Prerelease = true will come later with manifest support.
