JFROG_CLI_DEPENDENCIES_DIR defaults to /usr/dependencies when JFrog CLI is installed in /usr/bin

[nugins99]

Describe the bug

We have JFrog plugin installed via RPM in /usr/bin.

When doing this, the JFrog plugin uses /usr/bin/../dependencies.

Current behavior

My Jenkinsfile has the following environment variables defined:

environment {
        JFROG_CLI_LOG_LEVEL="DEBUG"
        JFROG_CLI_HOME_DIR="${WORKSPACE}/build/.jfrog"
        JFROG_CLI_DEPENDENCIES_DIR="${WORKSPACE}/build/.jfrog/dependencies"
        JFROG_CLI_TEMP_DIR="${WORKSPACE}/build/.jfrog/tmp"
}

Running "env" in my Jenkins job yields the following output:

JFROG_BINARY_PATH=/usr/bin
JFROG_CLI_AVOID_NEW_VERSION_WARNING=1
JFROG_CLI_DEPENDENCIES_DIR=/usr/dependencies
JFROG_CLI_HOME_DIR=/home2/workspace/<project>/build/.jfrog
JFROG_CLI_LOG_LEVEL=DEBUG
JFROG_CLI_TEMP_DIR=/home2/jenkins/workspace/<project>/build/.jfrog/tmp

Reproduction steps

Use jfrog cli from RPM installed in /usr/bin

Expected behavior

If CLI is installed in /usr/bin the plugin detects that special case and uses $HOME/.jfrog or some other configurable directory that is writable by the Jenkins user.

If there is a way to properly handle this case, it should be documented where the environment variable should be set. (Setting it in the Jenkinsfile does not appear to work)
