Reading certs and keys when sending a message everytime #11
Description
Is your feature request related to a problem? Please describe.
Currently, the tlsClientCert option etc treat the value as a file path and reads the file content every time when sending a message. It's very inefficient.
Describe the solution you'd like
Treat these options as cert data instead of a file path.
