feat: rename and update build script for selective component compilation

# See the License for the specific language governing permissions and

# limitations under the License.

# -----------------------------------------------------------------------------

# This script enables selective compilation of specific TeraFlowSDN (TFS)

# components to facilitate faster development and debugging workflows.

#

# Instead of building the full set of components, developers can specify a

# subset of components to compile. The script temporarily overrides the

# TFS_COMPONENTS environment variable with the user-provided list, invokes

# the standard build process (build-only.sh), and restores the original

# environment afterwards.

#

# Purpose:

# - Speed up development iterations by limiting builds to relevant components.

# - Avoid manual modification of the TFS_COMPONENTS environment variable.

# - Provide a safe mechanism to temporarily override build configuration.

#

# How it works:

# 1. Stores the current value of TFS_COMPONENTS (if defined).

# 2. Parses user input to determine which components to build.

# 3. Sets TFS_COMPONENTS to the specified components.

# 4. Executes the existing build-only.sh script.

# 5. Restores the original TFS_COMPONENTS value automatically on exit

#    (whether the build succeeds or fails).

#

# Usage:

#   ./build_components.sh <component1> [component2] [component3] ...

#

#   or

#

#   ./build_components.sh "component1 component2 component3"

#

# Examples:

#   ./build_components.sh context device pathcomp service

#   ./build_components.sh "context device pathcomp service"

#

# Warning:

# - This script must be used with caution.

# - Some components have implicit dependencies on others. Modifying one

#   component may require rebuilding additional components even if their

#   source code has not been changed.

# - It is the developer's responsibility to ensure that all required

#   components are included in the build to avoid inconsistent or broken

#   states.

#

# Notes:

# - This script does not modify the persistent environment; changes to

#   TFS_COMPONENTS are temporary and scoped to the script execution.

# - It relies on the existing build-only.sh script located in the same

#   directory.

#

# -----------------------------------------------------------------------------

# Save previous TFS_COMPONENTS to revert them after the compilation is successful

PREV_TFS_COMPONENTS="${TFS_COMPONENTS:-}"

export TFS_GRAFANA_PASSWORD="admin123+"

# Disable skip-build flag to rebuild the Docker images.

export TFS_SKIP_BUILD="YES"

export TFS_SKIP_BUILD=""
