Convert wiki pages in to files in the docs directory and general docs file cleanups (#2165)
Created new files for pages that were in the wiki, but not already in the docs directory. Also made following fixes to  README.md and existing files in the docs directory:

* update bolt links to avoid redirect
* link to logging guide from logging section (README.md)
* fixed typo in Backup section and capitalization of Bitcoin Core (README.md)
* Alice does not need trampoline feature enabled (TrampolinePayments.md)
* link to 2021 edition of Trampoline PR (TrampolinePayments.md)
* fixed API examples and removed quotes from password (API.md)
* use --nodeIds for sendtoroute examples (TrampolinePayments.md and MultipartPayments.md)
* update CLI example 3 to use jq (Usage.md)
* fix typo in docs/FAQ.md
* updated Guide.md to point to all pages that are guides

# Customize Features
Eclair ships with a set of features that are activated by default, and some experimental or optional features that can be activated by users.
The list of supported features can be found in the [reference configuration](https://github.com/ACINQ/eclair/blob/master/eclair-core/src/main/resources/reference.conf).
To enable a non-default feature, you simply need to add the following to your `eclair.conf`:
```conf
eclair.features {
official_feature_name = optional|mandatory
}
```
For example, to activate `option_static_remotekey`:
```conf
eclair.features {
option_static_remotekey = optional
}
```
Note that you can also disable some default features:
```conf
eclair.features {
initial_routing_sync = disabled
}
```
It's usually risky to activate non-default features or disable default features: make sure you fully understand a feature (and the current implementation status, detailed in the release notes) before doing so.
Eclair supports per-peer features. Suppose you are connected to Alice and Bob, you can use a different set of features with Alice than the one you use with Bob. When experimenting with non-default features, we recommend using this to scope the peers you want to experiment with.
This is done with the `override-features` configuration parameter in your `eclair.conf`:
```conf
eclair.override-features = [
{
nodeId = "03864ef025fde8fb587d989186ce6a4a186895ee44a926bfc370e2c366597a3f8f"
features {
initial_routing_sync = disabled
option_static_remotekey = optional
}
},
{
nodeId = "<another nodeId>"
features {
option_static_remotekey = optional
option_support_large_channel = optional
}
},
]
```
