[client-v2] Remove dependencies on old projects

[chernser]

Description

Client-v2 is new implementation of old http client and it has own dependencies. However it still depends on clickhouse-http-client for a few classes. It should be fixed asap because complicates depedencies and may break something.

What should be done:

• remove any dependencies on clickhouse-http-client project
• review dependencies on other projects and identify what should be removed, too.

Important: this issue is linked to settings so it also should solve the problem with list of all client options. refer to the comment - main idea to have list of string constants somewhere so it can be passed to the setOption methods.
