This PR fix#5778.
Easy test case to reproduce the problem:
https://play.golang.org/p/CAMdrOHT7C1
Since `certStr` is empty string during first iteration `strings.Join()`
will merge empty line with first CA cert.
Extra `strings.TrimSpace` call will remove that empty line, before
certificate will be return.
* Start work on passing context to backends
* More work on passing context
* Unindent logical system
* Unindent token store
* Unindent passthrough
* Unindent cubbyhole
* Fix tests
* use requestContext in rollback and expiration managers
A buffer is used to ensure that we only remove certificates that are
both expired and for which the buffer has past. Options allow removal
from revoked/ and/or certs/.
* Add comments to every non-obvious (e.g. not basic read/write handler type) function
* Remove revoked/ endpoint, at least for now
* Add configurable CRL lifetime
* Cleanup
* Address some comments from code review
