Use profile in cay-pom.xml to handle GUROBI issue.

For now, If we want to use HeterogeneousOptimizer(using ILPSolver as its solver), we have to manually erase the following codes from pom.xml file.
```java
<excludes>
    <exclude>**/ILPPlanDescriptor.java</exclude>
    <exclude>**/ilp/**</exclude>
</excludes>
```
However, if we use profile, this issue can be handled by passing an argument in command line.
