Remove mysqld if the user can't use the tool

If I were to start mysql today I can't do that in the cloudshell.

For e.g. if I start it by default here is what I see:

suraj [ ~ ]$ mysqld

And even when I provide another folder in the home directory, these are the errors I see:

suraj [ ~ ]$ mkdir foo
suraj [ ~ ]$ mysqld --datadir `pwd`/foo

Currently Azure Linux ships a bulky package called mysql which has both mysqld (MySQL server) and the mysql (MySQL client). So I created an issue in the Azure Linux repo to see if we can split the package into mysql-client and mysql-server. I believe that we should keep the mysql client it can be used to connect to mysql servers hosted remotely.

Closing this issue, since we have mysql cli tool.
