Adds the `rewrite` command.
Currently this only allows to change snapshot information (like time,
hostname, label, tags etc.) but in future it can be extended to also
modify snapshot trees, i.e. the data referenced by the snapshot.
Also the `tag` command (which is actually only a special case of
`rewrite`) now only allows to change tags.

This PR brings support for environment variable substitution in config
files. This simply uses the [subst](https://github.com/fizyr/subst)
crate to parse all environment variables before parsing the toml, this
allows to define toml values in environment variables for more
flexibility.
Previously, this was using the global registry (via register_gauge!),
which doesn't support re-registering metrics in this way, so only the
first call to `PrometheusExporter::push_metrics` would succeed, while
any later calls would return a (nested) `prometheus::Error::AlreadyReg`.
This resulted in only the metrics for the first snapshot being pushed,
while the metrics for subsequent snapshots errored with a somewhat vague
error (the interior messages are not shown):
```
[WARN] error pushing metrics: pushing prometheus metrics
```
This PR more closely matches the behavior of the OpenTelemetry backend,
which similarly only pushes the immediately-passed (as an argument)
metrics, rather than including other metrics previously registered
globally, as was the behavior with `prometheus::gather`.
There are likely less allocation-happy ways to solve this, but at the
push frequency of rustic it doesn't matter.

<blockquote>
<h2>tracing-subscriber 0.3.20</h2>
<p><strong>Security Fix</strong>: ANSI Escape Sequence Injection
(CVE-TBD)</p>
<h2>Impact</h2>
<p>Previous versions of tracing-subscriber were vulnerable to ANSI
escape sequence injection attacks. Untrusted user input containing ANSI
escape sequences could be injected into terminal output when logged,
potentially allowing attackers to:</p>
<ul>
<li>Manipulate terminal title bars</li>
<li>Clear screens or modify terminal display</li>
<li>Potentially mislead users through terminal manipulation</li>
</ul>
<p>In isolation, impact is minimal, however security issues have been
found in terminal emulators that enabled an attacker to use ANSI escape
sequences via logs to exploit vulnerabilities in the terminal
emulator.</p>
<h2>Solution</h2>
<p>Version 0.3.20 fixes this vulnerability by escaping ANSI control
characters in when writing events to destinations that may be printed to
the terminal.</p>
<h2>Affected Versions</h2>
<p>All versions of tracing-subscriber prior to 0.3.20 are affected by
this vulnerability.</p>
<h2>Recommendations</h2>
<p>Immediate Action Required: We recommend upgrading to
tracing-subscriber 0.3.20 immediately, especially if your
application:</p>
<ul>
<li>Logs user-provided input (form data, HTTP headers, query parameters,
etc.)</li>
<li>Runs in environments where terminal output is displayed to
users</li>
</ul>
<h2>Migration</h2>
<p>This is a patch release with no breaking API changes. Simply update
your Cargo.toml:</p>
<pre lang="toml"><code>[dependencies]
tracing-subscriber = "0.3.20"
</code></pre>
<h2>Acknowledgments</h2>
<p>We would like to thank <a href="http://github.com/zefr0x">zefr0x</a>

<code>security@tokio.rs</code>.</p>
<p>If you believe you have found a security vulnerability in any

By default, rhai support for filtering snapshots (`--filter-fn`) is now
not compiled in, but the compile feature still exists.
In future we might remove it completely as we now have `filter-jq` with
similar possibilities.
Adds the possibility to compare two snapshots interactively.
From the interactive snapshots view, press `D` to get to the diff view.
If two snapshots are marked, this diffs the two marked snapshots. If one
snapshot is marked or selected, this diffs with its parent (if there is
one).
Alternatively, you can use `rustic diff -i` to select snapshots/paths
directly.
The PR also allows to recursively compute added/removed space for dirs
and subdirs using `s` (like in #1479)
This PR is breaking as it also changes the output format of the normal
`diff` command.
If no grouping is given, the json output now displays all snapshots
without artificial grouping.
Also, in this case, the group is not displayed in non-json output.
closes#1362
This PR extends the logging. For `backup`, `forget`, `prune` the stdout
output is now printed via an INFO log which allows to see this
information also in the log file.
Moreover, when using a log file, rustic now also logs the version and
the used command.
closes#1454closes#1080
Note: This does not **use** the latest rustic core, but makes the
necessary modifications to make it work with `rustic_core` after the
latest dependency updates.
