Update LogicMonitorClient.cs

[MirkoFl]

Hello everyone,
In our project, I need to set an additional header on the Http client. As the Http client is not accessible, this was not possible until now.
My modification adds a new constructor. This takes an Http client in addition to the options and then sets this in the private property.
