More Link-header paging

[Jericho]

@kevinchalet recently alerted me to the fact that SendGrid includes "link" information in the response of the GlobalSuppressions.GetAllAsync which can be useful for pagination. While investigating this situation, I found out that there are other SendGrid API endpoints that also return this 'Link' information therefore it makes sense to modify StrongGrid so their corresponding methods include this information.

I asked SendGrid for their assistance figuring out the list of endpoints that return this information and I am waiting for a reply but in the mean time here is the list that I found.

• WebHooksSetting.GetAllInboundParseWebhookSettingsAsync GET user/webhooks/parse/settings
• Teammates.GetAllTeammatesAsync GET teammates
• Teammates.GetAllPendingInvitationsAsync GET teammates/pending
• SpamReports.GetAllAsync GET suppression/spam_reports
• SenderAuthentication.GetAllLinksAsync GET whitelabel/links
• SenderAuthentication.GetAllReverseDnsAsync GET whitelabel/ips
• SenderAuthentication.GetAllDomainsAsync GET whitelabel/domains
• IpAddresses.GetAllAsync GET ips
• ApiKeys.GetAll GET api_keys
• Blocks.GetAllAsync GET suppression/blocks
• InvalidEmails.GetAllAsync GET suppression/invalid_emails
