Add actual Ceph version to the log

[gbregman]

Right now we display the version we used to build the vstart cluster. But, we don't know which Ceph is actually used with the gateway. We should add this information to the log to help us debug future issues.

@rahullepakshi , @caroav when the change is committed we'll get the following line in the log:

ceph-nvmeof-nvmeof-1  | INFO:control.state:Connected to Ceph with version "18.2.0 (5dd24139a1eada541a3bc16b6941c5dde975e26d) reef (stable)"

Is there anything you would like to change there?

Above, 18.2.0 is still not giving exact ceph version. The more appropriate exact version would be from below example,
Upstream - ceph version 18.0.0-6774-g07872628 (0787262864508935dbafefdc86caa2c7957d776e) reef (dev)
or
ceph version 18.2.0-99.el9cp (3907976ec457510fcff7ac9039193741cf5c7d2b) reef (stable)

@rahullepakshi this text is what you get from Ceph when asking for a version. In your environment, with a different version of Ceph running you will get a slightly different text.

@rahullepakshi this is what I get in the Ceph container when asking for the version:

bash-5.1$ ceph version
ceph version 18.2.0 (5dd24139a1eada541a3bc16b6941c5dde975e26d) reef (stable)
bash-5.1$
