Azure timeout updates and minor cleanup

[sseraj]

Purpose

I updated the timeouts in Azure and also made some minor maintenance changes:

• Added a 10 minute time limit to the short jobs like style checks (closes #14)
• Reduced the time limit for the build and test jobs from the max of 6 hours to 2 hours (motivated by recent pyAeroStructure and pyGeo PRs)
• Removed defaults in the Tapenade subtemplate because I don't think we would ever use it outside the main template
• Removed the SKIP_TESTS parameter which was not used and did not make much sense to keep around
• Reordered some parameters for consistency (no functionality change)

Expected time until merged

One week
