move erddap maintiance scripts to same server as erddap ie catalogue.hakai.org

[fostermh]

from the readme

All views and tables generated from the different SQL queries made available in the view directory are run nightly from the hecate.hakai.org server from the master branch with the bash script [erddap_create_views.sh](https://github.com/HakaiInstitute/hakai-erddap/blob/master/erddap_create_views.sh)

the erddap create scripts should be moved to catalogue.hakai.org so they are on the same server as erddap. having the maintenance scripts on a difference server is confusing.
