Description of problem:

Currently oscap policy name field accepts more than 255 chars and this needs to be checked while adding it in the field itself.

We face the below issues while clicking the submit button.

PGError: ERROR: value too long for type character varying(255) : INSERT INTO "scaptimony_policies" ("created_at", "cron_line", "day_of_month", "description", "name", "period", "scap_content_id", "scap_content_profile_id", "updated_at", "weekday") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10) RETURNING "id"
