The --quiet option does not make sense in the interactive mode so it isn't
forwarded.
Added code that reports TLS certificate loading errors. The errors
themselves aren't very exact but at least they give a hint as to why it
failed.
It is frequently used when using self-signed certificates so making it
shorther makes life easier. Also added the missing --tls-passphrase into
the TLS options group.
Displaying the MaxScale version helps identify which package the
executable was bundled with. As the MaxCtrl source is a part of MaxScale,
there's no need for separate versioning.
The `drain server` commands removes a server from all services and waits
until all the connections for it are closed. Once the server is no longer
in use, it will be set into maintenance mode and put back into the
services where it was removed from.
Being able to perform raw REST API calls that leverage the value
extraction capabilities of Node.js gives more control to the end user. It
also doubles as a handy tool for creating scripts that only require one
particular value from the REST API.
When the -p parameter is given without an argument, the password is read
from the command line. This allows passwords to be given to MaxCtrl in a
safer manner.
MaxCtrl now supports explicit paths for certificates and optional server
certificate verification. This allows testing by using a self-signed
certificate with the server certificate verification turned off.
Using commas instead of spaces prevents a the misinterpretation of
commands as hostnames. If the `--hosts` option was given just before a
command, it would consume the commands as arguments to the `--hosts` list.
The messages now show where the request failed and what was
requested. This should help resolve both develper and end-user problems.
Also fixed the missing logging of the output string in the `parse`
callback of the main function and cleaned up the POSTed server body.
