Update issue template with user journey, persona label additions, and clarification between success metrics and acceptance criteria

The expansion hover animation caused a number of layout headaches; this
commit removes the animation and replaces them with hover/active/focus
styles.

API for importing external repos

Closes #52636

See merge request gitlab-org/gitlab-ce!22809

This change will instantiate an OpenTracing tracer and configure it
as the global tracer when the GITLAB_TRACING environment variable is
configured. GITLAB_TRACING takes a "connection string"-like value,
encapsulating the driver (eg jaeger, etc) and options for the driver.

Since each service, whether it's written in Ruby or Golang, uses the
same connection-string, it should be very easy to configure all
services in a cluster, or even a single development machine to be
setup to use tracing.

Note that this change does not include instrumentation or propagation
changes as this is a way of breaking a previous larger change into
components. The instrumentation and propagation changes will follow
in separate changes.
