[Libfix] Remove get_gluster_version() checks

Problem:
When run for nightly gluster builds dht cases fails
with below traceback:
```
    def get_gluster_version(host):
        """Checks the gluster version on the nodes

        Args:
            host(str): IP of the host whose gluster version has to be checked.

        Returns:
            (float): The gluster version value.
        """
        command = 'gluster --version'
        _, out, _ = g.run(host, command)
        g.log.info("The Gluster verion of the cluster under test is %s",
                   out)
>       return float(out.split(' ')[1])
E       ValueError: could not convert string to float: '20200719.9334a8d\nRepository
```

This is due to nightly builds returning the below output:
```
$ gluster --version
glusterfs 20200708.cdf01cc

```

Instead of:
```
$ gluster --version
glusterfs 6.0
```

This is caused as while building the we use
`VERSION="${GIT_DATE}.${GIT_HASH}` which causes the version
API to return new output.

Solution:
Remove the checks and modify the function
to return string instead of float.
