Astroquery v0.4.7

[rachel3834]

Describe the bug
The most recent version of astroquery appears to have changed the caching behaviour of Vizier queries. In v0.4.6 Vizier query objects have a cache_location parameter which can be set to None to switch off caching. This is desirable when a TOM is deployed to a Cloud-based server for example, since setting a cache location is a little more complicated and can incur additional charges.

Reviewing the current astropy documentation, it was not immediately obvious how this behavior can be configured in the newer version.

We have bumped the poetry.lock version of Astroquery to 0.4.7
We still support earlier versions of astroquery, but vizier is not used in TomBase.
If you run into the above issue, you may need to restrict the astroquery version to astroquery = "<0.4.7" in your TOM.
