* whitepaper: Syncing changes from the 1.0 community review & contribution period.

Thanks everyone for amazing feedback! Apologies for a bit short period,
but the paper was sitting for 2y without changes, so it made sense to time
box 1.0 and allow structured work on further iterations.

Still, within [this community review & contribution period](https://docs.google.com/document/d/19am_KCYWU28ebLiIXv_P3ji96edxCTscVb4CzemXV5A/edit)
I counted 67 individual contributions (count of comment/suggestion bubbles, excluding my own and not counting individual discussion comments)
from 7 new contributors.

High level changes (suggested by community, but also clean up by me):

* Note on aggregatability and volume of metrics.
* Added non goals
* Changing example from temperature to memory gauge
* Add reasons for metric efficiency
* Added info about cardinality (new section)
* Mentioned metric data models
* Added info about types
* Metric time series vs count
* Addressing feedback on logs, traces
* Adding profile screenshot
* Cleaning up, simplifying correlation section
* Removing how to setup Prometheus with exemplars
* Transitions
* Box based monitoring refactor - changing "closed box" traditional
* Clarified SLO/SLA
* Added image and figure captions
* More automatic and non-intrusive instrumentation solutions in OSS
* Linking ebay paper
* Added gap around streaming API, not enough DBs and standarized query language
* Did grammarly pass for typos.

...and more.

As mentioned in [the doc](https://docs.google.com/document/d/19am_KCYWU28ebLiIXv_P3ji96edxCTscVb4CzemXV5A/edit) I went through
all additional and old feedback. It's now either addressed in this PR or added as
todos in [separate issues](https://github.com/cncf/tag-observability/issues?q=is%3Aissue+is%3Aopen+label%3Acn-o11y-whitepaper-v1.1)

I admit, it was fun to process that doc! Reminds me of year ago when I was, fully focused, writing my [book](https://www.oreilly.com/library/view/efficient-go/9781098105709/) on sligthly different topic.
