Set the output of xxx.head() with scroll bar

[jingyanjingyan]

Describe the bug
For xxx.head(), when the output is large, it is better set a scroll bar to the output area.

To Reproduce
Steps to reproduce the behavior:

1. %reload_ext adlmagics
2. %adl login --tenant microsoft.onmicrosoft.com
3. adl_accounts = %adl listaccounts --page_index 0 --page_account_number 30
4. adl_accounts.head(10)
5. jobs1 = %adl listjobs --account devtooltelemetryadla --page_index 0 --page_job_number 100
6. jobs.head(100) [job looks ok, it has scroll bar when there are too many jobs]
7. submit job
8. view job
9. adls_accounts = %adl liststoreaccounts --page_index 0 --page_account_number 30
10. adls_accounts.head(100) no scroll bar
11. folders = %adl liststorefolders --account devtooltelemetryadls
12. folders.head(1000) no scroll bar
13. files = %adl liststorefiles --account devtooltelemetryadls --folder_path input\intellij
14. files.head(500) no scroll bar
15. sample_data = %adl sample --account devtooltelemetryadls --file_path vifeng/AdlUnmappedEventCounts.tsv --file_type tsv --encoding utf-8 --row_number 500
16. sample_data.head(1000) no scroll bar

Expected behavior
Add scroll bar when the output is too much
Currently, it has "..." in the long data as following. But it does not list all data user need and take too much space, i think.
