* Implement scheduling_source attribute
This implements the attribute `scheduling_source` for hosts and services to show which endpoint is running the scheduler for the check.

- Highlight the Icinga agent
- Prefer SSH as fallback and add more detailed setup instructions
- Improve SNMP and add traps right after
- Explain nscp and wmi with URLs
- Drop discouraged nrpe instructions (checks and PNP customizations)
- Update Dependency examples with the Icinga Agent
This sources from recent discussions on community.icinga.com
and follows the updates with the distributed monitoring chapter for 2.11.
The `process-check-result` action can now optionally set the
`ttl` parameter. This overrules the configured freshness
check (check_interval).
The main idea behind this is to allow the external sender
to specify when the next check result is coming in.
For example, a backup script which should be run every
24h can specify the exact expected next check result.
The addition to the CheckResult class is necessary to
forward the check result throughout the cluster and
calculate the `next_check` value on each node. This
allows us to send in a check result on a satellite,
and the master determines the freshness and possible
notifications/state changes for Icinga Web 2.
This replaces the previous "dummy" CheckCommand, and the user won't
notice it. Provided performance data will be parsed the same way.
This saves a shell fork and check_dummy execution.
We're relying on this when creating cluster checks with Icinga 2 DSL
and more. If one does not have the plugins installed, this then also works.
fixes#5740
This commit adds documentation for
* custom attributes value types and nested dictionaries
* better introduction into apply rules and usage examples
* better apply for iterations and explanations
* notifications with users on the host/service objects explained in a dedicated chapter
* command arguments and set_if - which values are supported
* macro() as scoped function
* alternative host check command
This also changes all code and config snippets to use
three backticks instead of four spaces indent.

Main focus: Object attributes and their value types. Originates from the
API Event Streams patch to document their value types. Now applied to
the entire configuration objects chapter.
The API chapter and their value types has been changed to capitalized
type identifiers.
Value types are now explicitly told about inside monitoring basics. This
has been adopted into the Icinga 2 training material a long time ago
and finds its way into the docs too.
The CheckResult and PerfdataValue value types have been moved into the
advanced topics chapter. mkdocs doesn't like multiple `#` headings in one file
and did just hide it.
Also moved the Influxdb details into the features documentation where it
belongs.
Many small references and URLs to other chapters added.
E.g. dedicated chapters for object accessor examples, to better link against
time dependent thresholds.
Can serve as patch basis and reference for ITL documentation where the
value types are missing too.
This commit also fixes the non-requirement of "legacy-timeperiod" which
also is a default template import since 2.6.
This also fixes the state mapping issue.
fixes#4015
* Rename files to allow easy ordering
* Update links inside markdown according to new file names
* Move HTML links (<a>...</a>) to the end of the header lines
* This is necessary to allow mkdocs to parse headers correctly and display them in the TOC
* Following sed command was used: sed -i .bu 's/\(<a.*a>\) \(.*\)/\2 \1/g' $filename
