Currently, the client that performs HTTP requests for Geo pushes
is the same as the one that performs internal HTTP requests.

However, it causes problems with the following setups:

- Internal requests are configured to be via UNIX connections
- The Primary node is configured to be HTTP(S)

The UNIX client cannot do the request to HTTP(S).

This commit introduces a separate client for Geo requests.

In future, we'll need to perform http requests for Geo related
code area.

We cannot use retryable requests because:

- It's not necessary for the to be retryable
- In order to retry, the whole request body is stored in RAM,
while we need to stream large blobs of data

This commit:

- Extracts logging into a separate round tripper in order to
reuse it for other http requests by default
- Defines Do function that accepts raw request as an argument
