Problem:
plain send + recv with root_fs encrypted + placeholders causes plain recvs
whereas user would expect encrypt-on-recv
Reason:
We create placeholder filesytems with -o encryption=off.
Thus, children received below those placeholders won't inherit
encryption of root_fs.
Fix:
We'll have three values for `recv.placeholders.encryption: unspecified (default) | off | inherit`.
When we create a placeholder, we will fail the operation if `recv.placeholders.encryption = unspecified`.
The exception is if the placeholder filesystem is to encode the client identity ($root_fs/$client_identity) in a pull job.
Those are created in `inherit` mode if the config field is `unspecified` so that users who don't need
placeholders are not bothered by these details.
Future Work:
Automatically warn existing users of encrypt-on-recv about the problem
if they are affected.
The problem that I hit during implementation of this is that the
`encryption` prop's `source` doesn't quite behave like other props:
`source` is `default` for `encryption=off` and `-` when `encryption=on`.
Hence, we can't use `source` to distinguish the following 2x2 cases:
(1) placeholder created with explicit -o encryption=off
(2) placeholder created without specifying -o encryption
with
(A) an encrypted parent at creation time
(B) an unencrypted parent at creation time
- Substitute full words for both string name 'gridspec' and short form 'grid spec'
- Fix alignment and make spacing more consistent
- Fix fall of snapshots into buckets for the example to really reflect right-exclusiveness

I generally like when snippets are provided in a way which could be used without running as root, and uses sudo when applicable. This change allows for this.
It will, however print out one extra line, which is possible to remove by adding '>/dev/null' after '/etc/apt/sources.list.d/zrepl.list'.

This was merged to master prematurely as the job components are not decoupled well enough
for these signals to be useful yet.
This reverts commit 2c8c2cfa14.
closes#452
Primary goals:
- Scrollable output ( fixes#245 )
- Sending job signals from status view
- Filtering of output by filesystem
Implementation:
- original TUI framework: github.com/rivo/tview
- but: tview is quasi-unmaintained, didn't support some features
- => use fork https://gitlab.com/tslocum/cview
- however, don't buy into either too much to avoid lock-in
- instead: **port over the existing status UI drawing code
and adjust it to produce strings instead of directly
drawing into the termbox buffer**

package is now at 95% code coverage and the additional tests codify
all behavior specified in the docs
There is a slight change in behavior:
Intervals are now [duration) instead of (duration].
If the leftmost interval is not keep=all, the most recently created
snapshot will be destroyed if there are other snapshots within
that first interval.
Since we recommend keep=all all over the docs, and zrepl 0.3
will put holds on that snapshot if it is being replicated,
I feel like this is an acceptable change in behavior.

fixup of 0bbe2befce
This commit
- adds a configuration in which no step holds, replication cursors, etc. are created
- removes the send.step_holds.disable_incremental setting
- creates a new config option `replication` for active-side jobs
- adds the replication.protection.{initial,incremental} settings, each
of which can have values
- `guarantee_resumability`
- `guarantee_incremental`
- `guarantee_nothing`
(refer to docs/configuration/replication.rst for semantics)
The `replication` config from an active side is sent to both endpoint.Sender and endpoint.Receiver
for each replication step. Sender and Receiver then act accordingly.
For `guarantee_incremental`, we add the new `tentative-replication-cursor` abstraction.
The necessity for that abstraction is outlined in https://github.com/zrepl/zrepl/issues/340.
