[ZEPPELIN-1371]add text/numeric conversion support to table display
### What is this PR for?
We people in Twitter have great demand of adding a flexible drop down menu
for the columns in the tables which enables the text/numeric conversion.
This is because people want some columns to be of string type which, for
example, fits to the underlying DB definition.
The use cases of the change include:
1. For now sorting on the columns is always lexicographically because
Zeppelin front end treats the data as strings. It the values in the table can
be convertible between string and number then we can sort the column by numeric
values. I have filed another ticket for this:
https://issues.apache.org/jira/browse/ZEPPELIN-1372
2. Since the users know more about their data than us it would be nice if
we let the users decide what is the real type of their data. It is annoying if
user wants the column to be strings but the front end forcefully inserts commas
in it. In some scenarios, users may also want to copy/paste the table to
somewhere else. If people want to remove the commas before other actions then
that will be a nightmare....
