Before this PR, config parsing would accept duplicate job names.
`zrepl daemon` would later fail to start with a panic.
But tools like `zrepl configcheck` would pass.
This PR adds a check to ensure job names are unique.
Similarly, internal job names were not being rejected by config
parsing
Move that check to parse-time as well.
This PR allows for the distribution of zrepl job definitions across
multiple YAML files that are included from the main config.
```
global: ...
include:
- ./zrepl.yml.d
- /opt/zrepl.yml
- ...
```
Refer to the docs changes for details.

While investigating https://github.com/zrepl/zrepl/issues/700
I checked in on `zrepl status` dependencies and found that
`cview`, which was/is a fork of tview, appears to be unmaintained.
We switched to it 4.5 years ago in a58ce74.
Checking now, `github.com/rivo/tview` seems to be somewhat maintained
again.
I also checked what k9s uses because that tool came to mind as a Go
terminal UI app.
It does use `tview`, but, a fork that has diverged substantially.
Maybe in another 4.5 years stuff the ecosystem has consolidated...
