tea-build.88: Bearer Token + Speed Improvements

What changed in TEA:

✳️ Support for Bearer Tokens passed in on behalf of uses

• TEA will accept and validate EDL Tokens via a Authorization Bearer: header
• Token validation is relatively expensive, response cookies could be used after initial request
• EDL Apps must be in the same EDL App Group to facilitate use of shared tokens
• EULA acceptance is respect if applicable

✳️ Stand alone Public/Private Bucket files have been deprecated

• CF & TF Params have been removed
• Support has been removed from code

✳️ New EDL Maturity options

• TEA can now be pointed at SBX and SIT urs environments

✳️ Optional HEAD check suppression

• App Deployers can now use the new SuppressHeadCheck (CF) / suppress_head_check (TF) parameters to suppress head checks
• Suppressing HEAD checks will speed up over all download time, but will result in more ambiguous 404-type errors

✳️ Pre-Signed URLS are now only valid for 1 Hour

• Cache-Control validity is also tied to 1 hour. This is a limit of IAM (Assuming a role, FROM an assumed role)

✳️ Fixed cached resource timeout bug from build.86
