[Security Solution] Unfriendly error message when creating an invalid exception (#168213)

[e40pud]

Summary

Addresses #168213

With this PR we limit the length of the comments in exceptions to 30K characters. We took same approach as used in Cases. User will not be allowed to create/edit exception with the comment longer than 30K and validation error will be shown.

Right now if user tries to add a very long comment (above 32K characters) the server throws an exception due to the length limitation of the keyword type.

After the fix, user will see a validation error on putting very long text as a comment
