[RFE] Support for encrypted communication in `pmlogger`

[kurik]

This Feature Request is asking for support of encrypted communication (TLS) in pmlogger.

Namely two communication channels should have the possibility of using encrypted communication:

• pmlogger - pmcd
• with the upcoming pmlogger-push model in PCPv7 it is also the pmlogger - pmproxy channel

pmlogger -> pmcd does have an option of encryption already (all PMAPI clients do, via the pcps://xxxx host specification, instead of the default, implied --host pcp://xxxx connection string).

But for pmlogger push, this could indeed by added simplest implementation would be as an https://xxxx pmlogger command line specification, instead of the current http://xxxx string.

I was not aware of this - I am going to extend my tests with this scenario as well. Thanks.
