Fabrízio de Royes Mello e34218ce29 Migrate Continuous Aggregates to the new format

Timescale 2.7 released a new version of Continuous Aggregate (#4269)
that store the final aggregation state instead of the byte array of
the partial aggregate state, offering multiple opportunities of
optimizations as well a more compact form.

When upgrading to Timescale 2.7, new created Continuous Aggregates
are using the new format, but existing Continuous Aggregates keep
using the format they were defined with.

Created a procedure to upgrade existing Continuous Aggregates from
the old format to the new format, by calling a simple procedure:

test=# CALL cagg_migrate('conditions_summary_daily');

Closes #4424
