hotfix: race condition

[becelot]

Fixes a race condition that can occur if more than one ccp service was requesting resources at the same time.

This happened due to the following pattern:

// start of every terraform provider resource implementation
c := m.(*client.Client)

c.HostURL = c.ServiceURLs["ssl-monitoring"]

By accident, c was a globally shared resource. Hence, when two services set the HostURL at approximately the same time, the HostURL was overwritten for the first service, and the wrong endpoint was used.

To fix this issue, every service now has a copy of the client with the correct HostURL already set. The above pattern can therefore be shortened to

c, err := m.(*client.CcpClient).GetService("ssl-monitoring")
