log manager options

[everettraven]

Description of the change

Add logging of the manager options for both the helm and hybrid operator commands

Motivation for the change

resolves #24

[joelanford]

Will it be confusing for the logs to include output for unset or unused flags?

For example, this is going to output something like: LeaderElectionId="", LeaderElectionNamespace="" even if leader election is disabled. Is that what we want?

[everettraven]

That's a good point. I think if leader election is disabled it is likely not important to log those values. I will work on making it so those values are only logged if they are set.

[everettraven]

As of commit 37c3d87 it should only show the options that have been specified via the flags or have a default value.

The output will now look like this with both leader election related flags:

{"level":"info","ts":1652113560.2827275,"logger":"cmd","msg":"Setting manager options:","Options":{"HealthProbeAddress":":8081","LeaderElection":true,"LeaderElectionId":"1","LeaderElectionNamespace":"test","MetricsBindAddress":":8080"}}

With only one:

{"level":"info","ts":1652113924.1076055,"logger":"cmd","msg":"Setting manager options:","Options":{"HealthProbeAddress":":8081","LeaderElection":true,"LeaderElectionId":"1","MetricsBindAddress":":8080"}}

With neither:

{"level":"info","ts":1652113954.4604402,"logger":"cmd","msg":"Setting manager options:","Options":{"HealthProbeAddress":":8081","LeaderElection":false,"MetricsBindAddress":":8080"}}
