    [FLINK-441] Rename Pact* and Nephele* classes in the optimizer

    Renames the package `org.apache.flink.compiler` to `org.apache.fink.optimizer`
    Renames `PactCompiler` to `Optimizer`
    Renames `NepheleJobGraphGenerator` to `JobGraphGenerator`
    Renames `PactConnection` to `DagConnection` (since the enclosing data structure is the
Optimizer DAG).
    Renames instances of internal variables and methods that referred to `PactContract` to
refer to `Operator` instead.
    
    Removes the unnecessary context checker. Was only ever valuable in the deprecated record
API.
    
    Makes the various graph traversals (previously inner classes of the Optimizer) standalone
classes, which makes the Optimizer class more graspable.
    
    Migrates some changes from the deprecated Record API to the Java API.

> I would like to do a cleanup and renaming in the pact-compiler. Most of the work is in
line with the recent global renaming, but I also want to clear and organize the various representation
structures for the optimized plan. 
> I open this issue to keep track and discuss the suggested renaming.
> We'll have to coordinate the merging of this issue because some renamings (e.g. PactCompiler
-> Compiler) seem to affect a lot of other packages.
> ### Global Scope (Wide Dependencies)
> The following names are part of the public API of stratosphere-compiler. Their renaming
will probably affect a lot of other modules.
> In ```eu.stratosphere.compiler```:
> * ```PactCompiler``` ⇒ ```Compiler```
> ### Module Scope (Narrow Dependencies)
> The following names are part of the internal API of stratosphere-compiler. Their renaming
will probably affect only stratosphere-compiler and stratosphere-tests.
> In ```eu.stratosphere.compiler```:
> * ```DataStatistics``` ⇒ ```StatsStore``` This should be developed as an API for data
stats over *expressions* instead of just over *data sources*.
> * ```NonCachingDataStatistics``` ⇒ *delete*. This class does not seem to be used.
