Add DAG name to the prefix as base configuration for all DAGs

[kamandir]

Hey All!

It happens to receive emails from DAGU about failed jobs. It has all the info about all the steps and what failed, but it misses the DAG name.
I know it is possible to add the errorMail configuration block into each and every DAG and specify the prefix to include the DAG name, but I believe there should be the option to make it from the base config. e.g. define it like the following (just as an idea):

Error mail configuration

errorMail:
from: "[email protected]"
to: "[email protected]"
prefix: "[Error in $DAG_NAME_VARIABLE]"

thanks and have a great weekend!
