This commit adds template rendering to the `proxmox-notify` crate, based
on the `handlebars` crate.
Title and body of a notification are rendered using any `properties`
passed along with the notification. There are also a few helpers,
allowing to render tables from `serde_json::Value`.
'Value' renderers. These can also be used in table cells using the
'renderer' property in a table schema:
- {{human-bytes val}}
Render bytes with human-readable units (base 2)
- {{duration val}}
Render a duration (based on seconds)
- {{timestamp val}}
Render a unix-epoch (based on seconds)
There are also a few 'block-level' helpers.
- {{table val}}
Render a table from given val (containing a schema for the columns,
as well as the table data)
- {{object val}}
Render a value as a pretty-printed json
- {{heading_1 val}}
Render a top-level heading
- {{heading_2 val}}
Render a not-so-top-level heading
- {{verbatim val}} or {{/verbatim}}<content>{{#verbatim}}
Do not reflow text. NOP for plain text, but for HTML output the text
will be contained in a <pre> with a regular font.
- {{verbatim-monospaced val}} or
{{/verbatim-monospaced}}<content>{{#verbatim-monospaced}}
Do not reflow text. NOP for plain text, but for HTML output the text
will be contained in a <pre> with a monospaced font.

This commit adds a way to filter notifications based on severity. The
filter module also has the necessary foundation work for more complex
filters, e.g. matching on properties or for creating arbitarily complex
filter structures using nested sub-filters.
