feat(conprof): show conprof download link for TiCDC

[baurine]

What Did

This PR supports to view TiCDC conprof status.

TODO: test compatibility with old versions (7.1, 6.5. 6.1)

Test

Test in 7.3.0, 7.1.0, 6.5.3, 6.1.0.

6.1.0 doesn't show TiCDC component in conprof, because the ngm of this version doesn't support TiCDC.

others all show TiCDC component in conprof.

Preview

Run dev env:

$ tiup playground 
$ tiup cdc server --addr 127.0.0.1:8301

The cluster and cdc are both 7.3.0 version.

Note: in my test environment, the ngm can't get the TiCDC profiles successfully, don't know why, so in the above screenshot, the status is Partial Finished, and in the detail page, the status for TiCDC is Error, clicking the Error Information, it will show the error reason in the modal.

LGTM, but why the second pic shows the connection refused? What does that mean?

LGTM, but why the second pic shows the connection refused? What does that mean?

It's the ngm service error, I don't know why it doesn't work normally, need @mornyx 's help. But for frontend, it shows the correct content from the API.

[mornyx]

I successfully deployed on the feature branch and no errors were repeated. I think we can assume that this feature is OK, the problem is the environment.

So LGTM
