getCertificate (scripted, public)
<instance of letsencrypt::Client> getCertificateThis method does all the steps required to obtain a certificate, such as - selecting the API (production or staging), - registering a new account if necessary, - create public and private key for the account, - issuing a certificate request, - obtaining the certificate, and - installing the certificate. If called interactivaly, the progress is logged to the console, otherwise just into the system log.
