> The old {{HColumnDescriptor(String)}} is deprecated and going away. The most straightforward
replacement for it is very wordy: {{ColumnFamilyDescriptorBuilder.newBuilder(byte \[]).build()}}
> We can provide a more inline replacement like {{ColumnFamilyDescriptor.for(String)}}
that will be useful if we do not need to actually do any modifications on it, only pass it
as an argument to something (like table descriptor operations).
> We can do the same kind of improvement for TableDescriptor, but I do not think the use
case is as helpful because usually we will want to do something to the modifiable TableDescriptor,
and I have not seen many use cases where it is passed as an argument unadorned.
