* Troubleshooting.md updates
Adds solutions to #1067 to the troubleshooting faq. Also moves a couple of answers to correspond to the headers.
* Change to Algo, strongly rec Ubuntu 18.04
Adds "Algo VPN" to the organization in the "Profiles" menu of "General Settings". (The type still shows up as "Unknown" in the "VPN" menu, because that seems to be governed by the "VPNSubType" string, which must be empty according to the [developer reference](https://developer.apple.com/enterprise/documentation/Configuration-Profile-Reference.pdf) Maybe this can help clear the way for #1101.
* Add documentation on how to setup GCE accounts
This commit adds the steps needed to create a credential with the needed access on Google Cloud Platform to be able to successfully create a new algo VPN.

* Adds links on main README to GCP
* Adds link to Ansible documentation
* Update cloud-gce.md
* Allow more flexible DNSCrypt configuration
* Correct permissions on files changed in #1120
I'm not sure why using BBEdit over SMB makes every file executable.
* Put the public resolvers cache file in /tmp.
This is to better document the "encryption" flag for those who are interested in full disk encryption on AWS. Recently on running the script, I also found the minimum permissions documented at https://github.com/trailofbits/algo/blob/master/docs/deploy-from-ansible.md weren't enough; "ec2:CopyImage" is also required. Not sure if you'd rather have this documented in the AWS docs instead, and not sure if you want "ec2:CopyImage" added to the default minimum required permissions. I can do either if you'd prefer.
The spacing of several lines in the congrats message has been off. Here's the congrats output with this fix:
```

" \"# Shell access: ssh -i configs/algo.pem ubuntu@54.85.244.8 #\"\n"
]
}
```
Ansible2.5 allows Algo to directly ask AWS for the region list, rather than have it hardcoded and updated manually. Updated the documented minimum required permissions to include "DescribeRegions".
