sperf core schema incorrectly identifies SAI and SASI indexes as Solr indexes

[msmygit]

sperf core schema incorrectly categorizes SAI and SASI indexes as Solr indexes.

For examples all the below are currently considered as Solr Index:

• CREATE CUSTOM INDEX sasi_index_01 ON ks1.tbl1 (evcid) USING 'org.apache.cassandra.index.sasi.SASIIndex' ;
• CREATE CUSTOM INDEX ON calendar2(years) USING 'StorageAttachedIndex';
• CREATE CUSTOM INDEX test1_tbl1_solr_query_index ON test1.tbl1 (solr_query) USING 'com.datastax.bdp.search.solr.Cql3SolrSecondaryIndex';
