Benchmarks post results to elasticsearch, but the TLS certificates of
https://benchmarks.leap.se and https://moose.leap.se are currently
expired. Automated LetsEncrypt certificate renewal must be configured
before benchmarks can be enabled again.

e2e tests currently depend on client dev environment running a platform
with blobs enabled. As the platform currently doesn't integrate with
blobs, any deploy to cdev environment breaks blobs configuration and
thus breaks e2e tests.

I am disabling these tests for now so we don't depend on them to have
packages built for soledad.

- move stream api doc to api section
- refactor section structure of blobs sync doc page
- improve wording a bit here and there

download was being inferred. It's now being set on each and will raise
an error if node is provided. Also removed a duplication on params
variable.

Stream production wasn't pausing or stopping as asked by protocol.

Was too high due a left over from some bug hunting. 20 is enough to
check both zero sized and under/equal/above tag size.

As it's blocking and Twisted already stored everything on a file.
