9465b593f9 cmd: configurable logrus formatters
We lost the nice context-stack [jobname][taskname][...] at the beginning
of each log line when switching to logrus.

Define some field names that define these contexts.
Write a human-friendly formatter that presents these field names like
the solution we had before logrus.

Write some other formatters for logfmt and json output along the way.

Limit ourselves to stdout logging for now.

ugly hack with relativ URLs because relref is apparently broken when

6a05e101cf WIP daemon:
Implement
* pruning on source side
* local job
* test subcommand for doing a dry-run of a prune policy

* use a non-blocking callback from autosnap to trigger the depending
jobs -> avoids races, looks saner in the debug log

e70b6f3071 WIP: recurring jobs
Done:

* implement autosnapper that asserts interval between snapshots
* implement pruner

* job pull: pulling + pruning
* job source: autosnapping + serving

TODO

* job source: pruning
* job local: everything
* fatal errors such as serve that cannot bind socket must be more
visible
* couldn't things that need a snapshotprefix just use a interface
Prefixer() instead? then we could have prefixsnapshotfilter and not
duplicate it every time...
* either go full context.Context or not at all...? just wait because
community climate around it isn't that great and we only need it for
cancellation? roll our own?

ce25c01c7e implement stdinserver command + corresponding server
How it works:

`zrepl stdinserver CLIENT_IDENTITY`
 * connects to the socket in $global.serve.stdinserver.sockdir/CLIENT_IDENTITY
 * sends its stdin / stdout file descriptors to the `zrepl daemon` process (see cmsg(3))
 * does nothing more

This enables a setup where `zrepl daemon` is not directly exposed to the
internet but instead all traffic is tunnelled through SSH.
The server with the source job has an authorized_keys file entry for the
public key used by the corresponding pull job

 command="/mnt/zrepl stdinserver CLIENT_IDENTITY" ssh-ed25519 AAAAC3NzaC1E... zrepl@pullingserver

fa4d2098a8 rpc: re-architect connection teardown
Tear down occurs on each protocol level, stack-wise.

Open RWC
Open ML (with NewMessageLayer)
Open RPC (with NewServer/ NewClient)
Close RPC (with Close() from Client())
Close ML
* in Server: after error / receive of Close request
* in Client: after getting ACK for Close request from Server
Close RWC

To achieve this, a DataType for RPC control messages was added, which
has a separate set of endpoints. Not exactly pretty, but works for now.

The necessity of the RST frame remains to be determined. However, it is
nice to have a way to signal the other side something went terribly
wrong in the middle of an operation. Example: A frameBridingWriter fails
to read the next chunk of a file it is supposed to send, it can just
send an RST frame to signal this operation failed... Wouldn't trailers
make sense then?

73c9033583 WIP: Switch to new config format.
Don't use jobrun for daemon, just call JobDo() once, the job must
organize stuff itself.

Sacrifice all the oneshot commands, they will be reintroduced as
client-calls to the daemon.
