tasks/upgrade: add basic upgrade testcase

Based on pre-generated tarball with PostgreSQL data - download the
tarball, unpack and perform 'postgresql-setup upgrade'.

* lib_pgsql.sh (dtf_postgresql_unpack_remote_data): New function.
(dtf_postgresql_upgrade_matrix): New function.  Detect which data
should we test against.
* run: Define new global $dtf_dataurl.
* tasks/upgrade-basic/config.sh: New testcase config.
* tasks/upgrade-basic/runtest.sh: New testcase.
