[che-dev] Dependency housekeeping

[Sergii Kabashniuk <skabashnyuk@xxxxxxxxxxx>]

Hi folks

Right now we are working on removing unapproved dependencies from our codebase. This dependency is not allowed to be used in any Che or Codenvy projects

         <dependency>

            <groupId>com.google.code.findbugs</groupId>

            <artifactId>jsr305</artifactId>

            <version>${javax.jcr350.version}</version>

        </dependency>

In order to replace it we are using 

Bean Validation API Version: 1.1.0.Final (PB CQ9025)  

       <dependency>

          <groupId>javax.validation</groupId>

            <artifactId>validation-api</artifactId>

            <version>${javax.validation.version}</version>

        </dependency>

or our custom annotation

       <dependency>

            <groupId>org.eclipse.che.core</groupId>

            <artifactId>che-core-commons-annotations</artifactId>

            <version>${project.version}</version>

        </dependency>

99% of replacement is

import javax.annotation.Nonnull;  -> import javax.validation.constraints.NotNull;

import javax.annotation.Nullable; -> import org.eclipse.che.commons.annotation.Nullable;

Also I'm asking you to review you custom branches. If you are  adding this annotation please make sure that after we apply this change in master you wouldn't add it again.
