Update analytics and share API URLs to refer to more stable locations

[peterkxie]

closes #1927
endpoints for analytics and sharing are now analytics.jbrowse.org and share.jbrowse.org

Used Route 53 to create the analytics and share subdomains of jbrowse.org

Both use alias redirects to Custom domain names in API Gateway under the same name

The custom domain names in API Gateway have API mappings to the existing endpoints that analytics and sharing sessions uses
