Update cluster file usage.

[johscheuer]

Description

Make use of dedicated cluster file for the fdb client lib and ensure to reuse it. The cli tooling will get a temp cluster file which will be deleted after the command was used.

Type of change

• Bug fix (non-breaking change which fixes an issue)

Discussion

Are there any design details that you would like to discuss further?

Testing

Ran e2e tests related to HA clusters.

I have to add another test in the e2e setup to see what happens when an operator is partitioned and all coordinators change (and no old coordinator is around) and how to resolve this case, in the previous setup a user could just update the SeedConnectionString.

Documentation

Will be updated before merging.

Follow-up

We should add a command in the kubectl plugin to update the connection string in the FoundationDBCluster status.
