* ui: Split up client/http and replace $.ajax
This splits the client/http service more in the following ways:
1. Connections are now split out into its own service
2. The transport is now split out into its own service that returns a
listener based http transport
3. Various string parsing/stringifying functions are now split out into
utils
* Remove jQuery from our production build
* Move the coverage serving to the server.js file
* Self review amends
* Add X-Requested-With header
* Move some files around, externalize some functions
* Move connection tracking to use native Set
* Ensure HTTP parsing doesn't encode headers
In the future this will change to deal with all HTTP parsing in one
place, hence the commented out METHOD_PARSING etc
* Start to fix up integration tests to use requestParams
Adds xhr connection managment to http/1.1 installs
This includes various things:
1. An object pool to 'acquire', 'release' and 'dispose' of objects, also
a 'purge' to completely empty it
2. A `Request` data object, mainly for reasoning about the object better
3. A pseudo http 'client' which doens't actually control the request
itself but does help to manage the connections
An initializer is used to detect the script element of the consul-ui sourcecode
which we use later to sniff the protocol that we are most likely using for API access
