Created Unassigned: Get-Package must support versions [18]

After calling Install-Package with a name and required version, I end up with multiple side-by-side installs, but Get-Package and Uninstall-Package don't know about versions __and do different things__. For example:


```posh
[326]: Install-Package Astley -Force

Name Version Status Source Summary
---- ------- ------ ------ -------
Astley 3.0 Installed chocolatey

[327]: Install-Package Astley -RequiredVersion 1.0 -Force

Name Version Status Source Summary
---- ------- ------ ------ -------
Astley 1.0 Installed chocolatey

[328]: Install-Package Astley -RequiredVersion 2.0 -Force

Name Version Status Source Summary
---- ------- ------ ------ -------
Astley 2.0 Installed chocolatey

[329]: Install-Package Astley -RequiredVersion 2.1 -Force

Name Version Status Source Summary
---- ------- ------ ------ -------

[331]: Install-Package Astley -RequiredVersion 2.2 -Force

Name Version Status Source Summary
---- ------- ------ ------ -------

[332]: Get-Package

```

Get-Package _ought, by default to return all versions_, not just the oldest. Get-Package and Uninstall-Package really also ought to have a way to return a specific one, this is ridiculous:

```
[334]: Get-Package Astley | Uninstall-Package

Name Version Status Source Summary
---- ------- ------ ------ -------
Astley 1.0 Not Installed


[335]: Get-Package Astley
