Document the troubleshooting process for provisioning profiles

[loudnate]

Document how to troubleshoot provisioning profile issues from the perspective of someone without a paid developer account. The Member Center is not available to those users, and profiles are automatically created by Xcode.

Here's what I've observed so far:

• The initial profile (created by running "Fix Issue") has an expiration date of 7 days
• The "next" profile (unsure how/when this can be forced) has an expiration date of 90 days

One of the harder to track-down issues is with Entitlements not being included when renewing a profile until the user navigates to the target's capabilities tab and flips the feature off-then-on-again. The only Entitlement-backed capability currently used by Loop is HealthKit.

Xcode 8 will help clarify things here, thankfully.

Thanks to @jlucasvt for adding the most common troubleshooting case here: https://github.com/loudnate/Loop/wiki/com.apple.developer.healthkit-Entitlement-Build-Error

Note that it appears the 90-day free profiles no longer apply; they are all 7 days. (thanks to @jlucasvt for finding the link)
