Fix UnicodeEncodeError while using PDB in baseclient.py _send_request
Motivation
----------
While using `remote_pdb` in a telnet client on `automatix` daemon pod in OKD4, when I try to use the `l` command to print the line numbers, `remote_pdb` throws `UnicodeEncodeError: 'ascii' codec can't encode character '\\u2019' in position 112: ordinal not in range(128)`. This is because the character on this comment line next to the word `server` in `baseclient.py` is not a ascii single quotation (27), but a unicode right single quotation (u2019): https://github.com/rucio/rucio/blob/9dc4238217a37b938f120b3bac2007487f6a063e/lib/rucio/client/baseclient.py#L367

The other single quotes in the code are standard ascii quotations, such as on this line: https://github.com/rucio/rucio/blob/9dc4238217a37b938f120b3bac2007487f6a063e/lib/rucio/client/baseclient.py#L92

Modification
------------
Change the right quotation to an ascii quotation.
