remove field cruft from Solr schema.xml for Argo - part 1.

[ndushay]

We have a bunch of cruft in our schema.xml file:

https://github.com/sul-dlss/sul-solr-configs/blob/master/argo_prod/schema.xml#L159-L164

FIELDS:

• text
• text_search
• text_unsteam_search
• date

These fields, AFAICT, either are empty or do not exist:

• http://sul-solr-prod-a.stanford.edu/solr/#/argo3_prod/schema (if you click "load term info" you get nothing)

We would like to remove them from schema.xml.

If I look at them with the schema browser at http://sul-solr-prod-a.stanford.edu/solr/#/argo3_prod/schema , I see a "delete field" button.

The work of this ticket:

1. find out what happens if we click the "delete field" button (do a little research? try it for qa? See if it sticks?)
   a. if useful, click the delete button for all 4 fields as needed
2. remove the fields from schema.xml for argo_prod, _stage, _qa (3_prod depending on Remove argo3_prod solr collection alias #4220)
3. remove https://github.com/sul-dlss/sul-solr-configs/blob/master/argo_prod/schema.xml#L188-L198 from schema.xml fields as well (?)
4. get these configuration updates propagated to argo Solr indexes in the cluster (see Solr cluster: how do we deploy updates to our config files (schema.xml, solrconfig.xml, etc) #4219)

cruft removed for -qa and -stage. Awaiting more testing before proceeding to prod.

and with sul-dlss/sul-solr-configs#278 and running zookeeper, updated Solr configs are deployed to all Argo solr collections.
