Include cagg name in timescaledb_information.jobs

[melihmutlu]

In the timescaledb_information.jobs view, it is not possible to see the
continuous aggregate name for jobs related to continuous aggregates and
it is necessary to use the materialized table id to look up the actual
continuous aggregate. Since hypertable_schema and hypertable_name
columns contain the materialized hypertable for the continuous
aggregate, which are considered internal objects and not very useful
except for looking up the continuous aggregate, we store the continuous
aggregate name and schema in these columns.

This seems to be implemented in #7976.

[mkindahl]

For jobs that belong to a continuous aggreagate, use cagg name and cagg schema in timescaledb_information.jobs view instead of internal hypertable name and schema.

Might be better to spell out details and avoid abbreviations, e.g., something along these lines (I usually elaborate a lot in my comments since I find it useful when you want to figure out why you did something as well as what you did, but you don't have to do that).
