Better indentation for SHOW QUERIES

[hjafarpour]

If multiple lines are used for a query, show query does not correctly indent the query content. Here is an example:

ksql> CREATE STREAM pageviews_enriched AS
>SELECT users_original.userid AS userid, pageid, regionid, gender
>FROM pageviews_original
>LEFT JOIN users_original
>  ON pageviews_original.userid = users_original.userid;

 Stream PAGEVIEWS_ENRICHED created and running. Created by query with query ID: CSAS_PAGEVIEWS_ENRICHED_2

ksql> show queries;

  PAGEVIEWS_ORIGINAL.PAGEID "PAGEID",
