Extract consul client builder to distinct bean

[stewartie4]

Users of spring cloud consul may wish to further modify the consul client

Example modifications:

• Custom SSL config
• Adding interceptors to the HTTP client
• Additional logging etc.

Today the builder is statically instantiated inside createConsulClient() therefore any modifications will require the user to copy and paste the boilerplate setup in createConsulClient(), then make modifications.

Extracting the client builder out to a separate bean allows a custom builder to be injected and therefore any modifications can be made without copy and pasting boilerplate code
