Expose a method GetRecentEffectiveConnectionType in NQE.

This method is private and will be used for computing the
accuracy of NQE.

Also, remove some duplicate code in the existing methods.

Record NQE accuracy at main frame requests

At each main frame request, NQE estimates are preserved
locally. Then, the observed network quality is computed
from the observations received in the next 15, 30 and 60
seconds. The preserved estimates are compared against the
observed estimates, and the computed accuracy is recorded
using UMA.

NQE: Allow algorithm to be set using variation params

This CL provides the ability to use different algorithms for
computing effective connection type. The algorithm to use
can be set using field trial params. If field trial params
are unavailable (e.g., at first run), then a default value
is used.

The existing algorithm was also modified to be exactly same
as what data reduction proxy is currently is using.

Once this CL lands, the server side CL needs to land to set
the variation param. Then, GetEffectiveConnectionType() API
will be ready for use by DRP and custom fonts.

Add function that converts string connection type to ECT

Field trials may specify the threshold ECT as a string (in
the field trial params). This function allows for easier
conversion from a string ECT to an enum ECT.

Change the visibility of NQE public functions

These functions expose raw metrics such as estimated HTTP
RTT, transport RTT, bandwidth. They can now all be
"protected" since data reduction proxy has switched to
GetEffectiveConnectionType().
