October 2020 Release: Post-sign redirect

Post-sign redirect set to zero seconds by default
As of this release, all redirects have a default 0-second delay to redirect to a new page.

- This applies to automatic redirects (eg: the post-signing page; integrations) and API calls
- API calls can configure redirect delay in the API call if a greater delay is desired

Post-sign redirect message added to the esigning page footer
If a redirect is configured for an agreement (via UI or API), a message is added to the Click to Sign footer of the esigning page to alert the recipient that they are going to be redirected after signing.

- The redirect message: "Upon signing, sender requests you be redirected to domain.com"
- domain.com is the domain name supplied in the specific URL redirect
