This PR adds support for oidc in mcs, to enable idp
authentication you need to pass the following environment variables and
restart mcs.
```
MCS_IDP_URL=""
MCS_IDP_CLIENT_ID=""
MCS_IDP_SECRET=""
MCS_IDP_CALLBACK=""
```
Trace Api uses websocket to send trace information, a
valid jwt token needs to be sent either on the header
or as a cookie of the ws request to start.
Three goroutines are needed to ensure communication
if read hearbeat fails all trace should stop by cancelling
the context. WaitGroups are needed to ensure all
goroutines finish gracefully.
This commit changes the authentication mechanism between mcs and minio to an sts
(security token service) schema using the user provided credentials, previously
mcs was using master credentials. With that said in order for you to
login to MCS as an admin your user must exists first on minio and have enough
privileges to do administrative operations.
```
./mc admin user add myminio alevsk alevsk12345
```
```
cat admin.json

updates code to be compatible with:
- github.com/minio/mc v0.0.0-20200415193718-68b638f2f96c
- github.com/minio/minio v0.0.0-20200415191640-bde0f444dbab
Note: admin_config api is patched temporarily now to
return the target configuration as a raw string due to the
changes done on minio.
