Clean Up after New Solr is released to PROD.

Following variables are still points to silver. Investigate if they are still in use. If no, removed the related codes too in Namex api.
auto-analyze ==> SOLR_SYNONYMS_API_URL: http://solr-synonyms-api-dev.f2b77c-dev.svc:8080/api/v1
namex-api ==> SOLR_BASE_URL:http://solr-dev.f2b77c-dev.svc:8983
namex-api ==> AUTO_ANALYZE_URL: http://auto-analyze-dev.f2b77c-dev.svc:8080 is dead codes?
auto-analyze2 ==> SOLR_SYNONYMS_API_URL: http://solr-synonyms-api-dev.f2b77c-dev.svc:8080/api/v1

namex-api ==> SOLR_BASE_URL_EXTERNAL: https://namex-solr-dev.apps.silver.devops.gov.bc.ca
solr-admin ==> SOLR_ADMIN_APP_OVERWRITE_REDIRECT_URI: https://namex-solr-dev.apps.silver.devops.gov.bc.ca/oidc_callback can be removed?
solr-admin ==> SOLR_ADMIN_APP_SOLR_INSTANCE: https://namex-solr-dev.apps.silver.devops.gov.bc.ca/solr can be removed?
solr-admin ==> SOLR_URL: https://namex-solr-dev.apps.silver.devops.gov.bc.ca can be removed?
solr-feeder ==> SOLR_FEEDER_SOLR_INSTANCE: https://namex-solr-dev.apps.silver.devops.gov.bc.ca/solr can be removed?
namex-web ==> URL: https://namex-dev.apps.silver.devops.gov.bc.ca
Investigate if auto_analysis_api is still in use.

Search the Namex API, auto-analyze, auto-analyze2, solr-admin, solr-feeder, and namex-web configuration for the listed Silver URLs and variables. First determine whether auto_analysis_api and each variable are still referenced; done means removing only confirmed-unused code or configuration and verifying the remaining references point to the new production Solr setup.
