Piotr Jastrzebski 2091408478 cdc: Make it possible for CDC generation creation to fail

Following patch enables CDC by default and this means CDC has to work
will all the clusters now.

There is a problematic case when existing cluster with no CDC support
is stopped, all the binaries are updated to newer version with
CDC enabled by default. In such case, nodes know that they are already
members of the cluster but they can't find any CDC generation so they
will try to create one. This creation may fail due to lack of QUORUM
for the write.

Before this patch such situation would lead to node failing to start.
After the change, the node will start but CDC generation will be
missing. This will mean CDC won't be able to work on such cluster before
nodetool checkAndRepairCdcStreams is run to fix the CDC generation.

We still fail to bootstrap if the creation of CDC generation fails.
