# Link to a Label
#
# label - Label object to link to
# subject - Project/Group object which will be used as the context for the
# label's link. If omitted, defaults to the label's own group/project.
# type - The type of item the link will point to (:issue or
# :merge_request). If omitted, defaults to :issue.
# block - An optional block that will be passed to `link_to`, forming the
# body of the link element. If omitted, defaults to
# `render_colored_label`.
#
# Examples:
#
# # Allow the generated link to use the label's own subject
# link_to_label(label)
#
# # Force the generated link to use a provided group
# link_to_label(label, subject: Group.last)
#
# # Force the generated link to use a provided project
# link_to_label(label, subject: Project.last)
#
# # Force the generated link to point to merge requests instead of issues
# link_to_label(label, type: :merge_request)
#
# # Customize link body with a block
# link_to_label(label) { "My Custom Label Text" }
#
# Returns a String
