   ### Is your feature request related to a problem or challenge?
   
   ANALYZE TABLE command is used to calculate statistics. Spark's documentation 
can be seen 
[here](https://spark.apache.org/docs/latest/sql-ref-syntax-aux-analyze-table.html)
   
   This can allow us to do things like: 
    - Accurately calculating distinct values (with the choice of just counting 
everything or using a hyperloglog)
    - Allowing the user to recalculate statistics and calculate them upfront 
instead of lazily if suspected statistics have gotten stale. 
    - Memtable stat calculations
   
   ### Describe the solution you'd like
   
   Something similar to spark's implementation makes sense
   
   Syntax:
   ```sql
   ANALYZE TABLE table_identifier 
     COMPUTE STATISTICS [ NOSCAN | FOR COLUMNS col [, ...] | FOR ALL COLUMNS ]
   ```
   
   `COMPUTE STATISTICS` (nothing else after it): Only calculate table stats 
(num_rows + total_byte_size)
   `NOSCAN`: Don't probe/scan any values - just return
   `FOR COLUMNS col [, ...]`: table stats + calculating specified columns stats 
(min, max, null, etc.)
   `FOR ALL COLUMNS`: All column stats are calculated (min, max, null, etc.)
   
    - when specified for specific columns; when it is under a certain amount of 
columns + row count. A direct computation of distinct count can be done. 
   
    - Maybe histogram support, this will need to be discussed if anything
    - Maybe a way to persist statistics
