This commit is to enable data migrator to support migrates data
from mysql to pgsql, this is a specific step for user to upgrade
harbor across v1.5.0, as we have move harbor DB to pgsql from
1.5.0. It supports both harbor and notary db data migration,
and be split into two steps with dependency.
It also fix issue #4847, add build DB migrator in make process.
Narrow down the scope of `chown` in adminserver because the
/etc/adminserver/config/ is the location to store the config.json file.
And /etc/adminserver/key should be readonly.
The following are done to avoid travis-ci failing due to too much log
size.
1) Update Makefile and scripts to make go build less verbose.
2) Make tdnf less verbose
This change reworked the vmware/harbor-db image to build it on top of
vmware/mariadb-photon.
Also made minor change in the entrypoint script of mariadb image to
execute upgrade script during bootstrap, and fix a file permission
issue in the bootstrap scripts.
