Added script and compiler option to run admin in debug mode

[pmahindrakar-oss]

Signed-off-by: Prafulla Mahindrakar prafulla.mahindrakar@gmail.com

TL;DR

Running admin in debug mode requires the compiler output to have debug bits.
Added a new Makefile target compile_debug which does this and the script debug.sh uses dlv to run the admin in debug mode for the serve option

Similarly the script can be modified to run for other commandline options exposed by flyteadmin

Pre-reequisite:
Install dlv : https://github.com/go-delve/delve/blob/master/Documentation/installation/README.md
Setup IDE Debug configuration. The port for DLV should match

Interesting can you debug the process in k8s? How? Do you have to start with delve

[pmahindrakar-oss]

@kumare3 this is only for admin running outside the k8 cluster. The locally running admin in the IDE can use the k8 deployed services of minio and postgres using port forwarding .

There is way to do the same for k8 deployed admin.
@EngHabu had suggested to use https://github.com/telepresenceio/telepresence/tree/release/v2
I haven't tried that yet because the current way of running admin in the IDE works for me.
We can try the telepresence route aswell if people are interested.
