Complete Description of Additions/Changes:

• Card ID: CCT-705

This patch will help us with identifying what is happening at given times.

• Include phase, version and arguments on each phase load. Some of the information may not be necessary, as newer builds of insights-client contain logs that carry the information about phase and version. However, older builds do not, and these bits are valuable when debugging.
• Disable logging of HTTP responses for collection rules and Inventory host. They are verbose and do not need to be logged in a file every time. The important parts of it are logged elsewhere.
