The existing docs described how to configure the DynamoDB registry, but
didn't have a tutorial for someone to walk through.

**Description**
In the current implementation, DNS providers are called to list all
records on every loop. This is expensive in terms of number of requests
to the provider and may result in being rate limited, as reported in 1293
and 3397.
In our case, we have approximately 20,000 records in our AWS Hosted Zone.
The ListResourceRecordSets API call allows a maximum of 300 items per call.
That requires 67 API calls per external-dns deployment during every sync period
With this, we introduce an optional generic caching mechanism at the provider
level, that re-uses the latest known list of records for a given time.
This prevents from expensive Provider calls to list all records for each
object modification that does not change the actual record (annotations,
statuses, ingress routing, ...)
This introduces 2 trade-offs:
1. Any changes or corruption directly on the provider side will be
longer to detect and to resolve, up to the cache time
2. Any conflicting records in the DNS provider (such as a different
external-dns instance) injected during the cache validity will cause
the first iteration of the next reconcile loop to fail, and hence add a
delay until the next retry
**Checklist**
- [X] Unit tests updated
- [X] End user documentation updated

Hey! I was trying out external-dns using cloudflare. I followed your docs and managed to deploy it successfully on my k3s cluster. While reading the docs and copying pasting the yaml files I noticed there was some inconsistencies with the indentation..
I am no kubernetes expert, I just fixed the problems that were not allowing me to deploy this service and checked the files using yamllint.com
While I was at it I also noticed a few errors on the syntax highlighting for code blocks, some had shell where the content was yaml, I fixed those too..
I hope this helps, thank you for this amazing project!
The secret includes keys/value pair and a secret, when mounted as a
volume, will generate a file for each of the pair where the name of the
file is the key and the content of the file, the value.
This hopefully makes the doc clear on how to configured credentials.
The Helm section includes templates files that aren't needed as those
values can all be generated from the values.yaml file. It seems that the
current documentation also missed the role arn annotation so it was
added as well.
