Schedules a ScheduledExecutorService to read trust certificates from a local file path periodically, and update the cached trust certs if there is an update.

Parameters:

trustCertFile - the file on disk holding the trust certificates

period - the period between successive read-and-update executions

unit - the time unit of the initialDelay and period parameters

executor - the execute service we use to read and update the credentials

an object that caller should close when the file refreshes are not needed

Throws:

IOException

GeneralSecurityException
