Add Bamboo UI scraping to retrieve Deploy Project Environment Tasks

[lholman]

@muratiakos This is WIP, I'd like to talk to you about it as it doesn't utilize the Bamboo API, as no endpoints exist that I could find that allow detail of Environment Tasks to be retrieved.
If you could take a look through and let me know what you think. Maybe we could have stricter version checks for these endpoints and provide some other indicator to consumers that they're from the UI, thoughts?

@muratiakos I'm getting different build results locally. Could you let me know what version of Pester you;re using and if you added anymore dependencies adding the AppVeyor build, I'm getting a failure not being able to find Get_Metadata
