[samikshya-db]

Description

• This is to support Discovery URL for U2M AWS and GCP in OSS JDBC [PECOBLR-15] Respect OAuth Discovery URL for ExternalBrowserCredentialsStrategy databricks-sdk-java#505 (Note azure is not supported as it has a different flow in OSS JDBC)

Testing

Tested that discovery URL is being honored in U2M as well. Tested this using the OSS JDBC with the following URL

1. Success flow test :

String jdbcUrl =
        "jdbc:databricks://e2-dogfood.staging.cloud.databricks.com:443/default;transportMode=http;ssl=1;httpPath=/sql/1.0/warehouses/dd43ee29fedd958d;"
            + "AuthMech=11;Auth_Flow=2;LogLevel=6;UseThriftClient=0;EnableTokenCache=0;OIDCDiscoveryEndpoint=https://e2-dogfood.staging.cloud.databricks.com/oidc/.well-known/oauth-authorization-server";

2. Failure flow test :

String jdbcUrl =
        "jdbc:databricks://e2-dogfood.staging.cloud.databricks.com:443/default;transportMode=http;ssl=1;httpPath=/sql/1.0/warehouses/dd43ee29fedd958d;"
            + "AuthMech=11;Auth_Flow=2;LogLevel=6;UseThriftClient=0;EnableTokenCache=0;OIDCDiscoveryEndpoint=https://google.com";

Also tested using GCP :

"jdbc:databricks://6177827686947384.4.gcp.databricks.com:443/default;transportMode=http;ssl=1;EnableTokenCache=0;AuthMech=11;Auth_Flow=2;httpPath=/sql/1.0/warehouses/f5e97c8f8dfb56b5;OIDCDiscoveryEndpoint=https://6177827686947384.4.gcp.databricks.com/oidc/.well-known/oauth-authorization-server";
