add lineage-driven fault injection

https://people.eecs.berkeley.edu/~palvaro/molly.pdf tl;dr: add faults and gracefully recover should be the outcome - or at least document failures so they are well understood. i.e.: fault tolerance is a global property. [molly.pdf](https://github.com/senior7515/smf/files/817176/molly.pdf)

Look into enabling cfi from clang on our production binaries. - requires a pretty modern compiler clang 6?

we have 2 types of patterns ``` struct foo_opts {} struct foo { foo (foo_opts) {} } ``` and ``` struct foo { struct opts {} foo(foo::opts) {} } ```...

revisit exception safety

We are breaking some laws regarding exception safety. see all the noexcept methods for instances.

split the Raft implementation into its own library

I was looking into building a replicated state machine and I really like this C++ implementation. I was wondering if the team has any interest in separating the log cabin...

Friendly build system for integrating into larger projects.

Was looking at adding this and realized that the headers are not scoped to say `include/fpfor/*` for example ``` #include "common.h" #include "codecs.h" #include "vsencoding.h" #include "util.h" #include "simple16.h" #include...

redpanda: low latency mode

hi @adamw - i saw the post (https://github.com/softwaremill/mqperf/commit/8873fa57cf554c720488b5ba5a09dfab92dd23d6?short_path=e28ac69#diff-e28ac696dc377acf5d4494af8b82c2fa6467c86cfea831bdd149c1d124eb5edf) when i was looking up redpanda projects. We just introduced a patch for even lower latency (at expense of lower throughput): https://github.com/vectorizedio/redpanda/commit/1b0f027dc0f61fbdbf06bf77440a1e863cc2e87e...

Depending on a particular workload there might be a situation in which the chunk appender, might take on full 32MB and wait to synchronize all 32MB in 16KB chunks. strategy...
