This commit adds new pages with reference to
Handling Node Failures to Troubleshooting.
The pages are:
- Failure to Add, Remove, or Replace a Node
(in the Cluster section)
- Failure to Update the Schema
(in the Data Modeling section)
This commit moves the content of the Handling
Failures section on the Raft page to the new
Handling Node Failures page in the Troubleshooting
section.
Background:
When Raft was experimental, the Handling Failures
section was only applicable to clusters
where Raft was explicitly enabled.
Now that Raft is the default, the information
about handling failures is relevant to
all users.
