After "Make replacing node take writes" series, with repair based node
operations disabled, we saw the replace operation fail like:
```
[shard 0] init - Startup failed: std::runtime_error (unable to find
sufficient sources for streaming range (9203926935651910749, +inf) in
keyspace system_auth)
```
The reason is the system_auth keyspace has default RF of 1. It is
impossible to find a source node to stream from for the ranges owned by
the replaced node.
In the past, the replace operation with keyspace of RF 1 passes, because
the replacing node calls token_metadata.update_normal_tokens(tokens,
ip_of_replacing_node) before streaming. We saw:
```
[shard 0] range_streamer - Bootstrap : keyspace system_auth range
(-9021954492552185543, -9016289150131785593] exists on {127.0.0.6}
```
Node 127.0.0.6 is the replacing node 127.0.0.5. The source node check in
range_streamer::get_range_fetch_map will pass if the source is the node
itself. However, it will not stream from the node itself. As a result,
the system_auth keyspace will not get any data.
After the "Make replacing node take writes" series, the replacing node
calls token_metadata.update_normal_tokens(tokens, ip_of_replacing_node)
after the streaming finishes. We saw:
```
[shard 0] range_streamer - Bootstrap : keyspace system_auth range
(-9049647518073030406, -9048297455405660225] exists on {127.0.0.5}
```
Since 127.0.0.5 was dead, the source node check failed, so the bootstrap
operation.
Ta fix, we ignore the table of RF 1 when it is unable to find a source
node to stream.
Fixes #6351
"
* asias-fix_bootstrap_with_rf_one_in_range_streamer:
range_streamer: Handle table of RF 1 in get_range_fetch_map
streaming: Use separate streaming reason for replace operation
