Speed: Use long caching times

[delisma]

Describe the bug
Configure page resources to have long caching times so browser caches will retain them for longer. The cache duration of each resource URL can be specified by either:

1. setting an Expires response header which specifies the point in time the response becomes stale such as Expires: Fri, 10 Aug 2019 20:00:00 GMT or
2. adding a max-age directive to the Cache-Control response header that specifies the number of seconds the response is valid for such as Cache-Control: max-age=3600 for 1 hour.

To Reproduce

1. satelliteLib-c2082deaf69c358c641c5eb20f94b615dd606662.js
   assets.adobedtm.com/caacec67651710193d2331efef325107c23a0145/
   satelliteLib-c2082deaf69c358c641c5eb20f94b615dd606662.js
   max-age 60
2. sig-blk-en.svg
   wet-boew.github.io/themes-dist/GCWeb/GCWeb/assets/
   sig-blk-en.svg
   max-age 10
3. wmms-blk.svg
   wet-boew.github.io/themes-dist/GCWeb/GCWeb/assets/
   wmms-blk.svg
   max-age 10
4. theme.min.css
   wet-boew.github.io/themes-dist/GCWeb/GCWeb/css/
   theme.min.css
   max-age 10
5. theme.min.js
   wet-boew.github.io/themes-dist/GCWeb/GCWeb/js/
   theme.min.js
   max-age 10
6. noscript.min.css
   wet-boew.github.io/wet-boew/wet-boew/css/
   noscript.min.css
   max-age 10

Expected behavior
If max-age and Expires are both used, max-age takes priority. Recommendation is to set the cache time of page resources to at least 24 hours.
