Provide a means for developers to download VCH certs and env file from UI

[stuclem]

Similar to goharbor/harbor#3117, everyone from the Developer role upwards should be able to download the certificates and the env files for their VCHs from the Management Portal. At the moment, in the docs we have to tell developers to ask their vSphere admin for these files, which isn't very high-tech.

I searched the open issues for something similar but didn't see anyway. Sorry if this is a dup.

The screenshots (shown in goharbor/harbor#3117) are coming from harbor UI and once that issue (3117) is resolved they'll be shown in admiral (eventually an increment of the harbor ui component version may be needed - depending on how harbor team fixes the issue - in the current version or producing a new one).

@lazarin goharbor/harbor#3117 is talking about the Registry certificate only. What I am talking about is making the VCH certificates, and ideally the VCH env file available in the UI too. Since you add VCHs in Admiral, my assumption was that it would Admiral's job to make the certs/env file available.

I would like to see some means for this as well. It seems a bit fragmented to let Devs log into Admiral with SSO, then have to arrange for some other means to get them certificates for VCH access.
