Guidance for versioning in CONTRIBUTING.md and fix for Remove-ITGlueAPIKey (#37)

* Add Support for Passwords API

With the release of API v1.8.0, a new Passwords endpoint was added.
This update uncovers that endpoint in the PowerShell module with the
addition of the following functions:
 - `New-ITGluePasswords`
 - `Get-ITGluePasswords`
 - `Set-ITGluePasswords`

Release notes for the Passwords api are available
[here](https://kb.itglue.com/hc/en-us/articles/360001797531-Release-Note
s-1-8-0-API).

——————

The Module Version was also updated to reflect the API version it
supports.

* Add support for EU API endpoints

API endpoints have been added for deployments in the EU datacenter.
This update uncovers the ability to use the EU API links by use of a
`-data_center` (or `-dc`) option on the `Add-ITGlueBaseURI` function.
This optional argument takes `EU` and `US` as options, however the US
datacenter is still kept as the default even if no arguments are given.

—

HTTPS is also set by default for both the US and EU data centers.

* Added enhanced filtering capability

Most endpoints (especially Index/Show, and Update) now allow for
expanded filtering capabilities. This updated exposes those new
capabilities as command parameters.

* Fixed Configurations Return Data

Fixed a bug that was pointed out that caused incorrect data to be
returned from the `Get-ITGlueConfigurations’ function.

* Compatability Update

All resources now match the current API spec given at
https://api.itglue.com/developer.

This includes enhanced bulk update, bulk destroy, and filtering
capabilities.

Thanks to @TheMattCollins0 for changes to make adding an API key via
command line easier.
