odo dev --debug: add flag to run non-default debug command

[rm3l]

User Story

• As an odo user
• I want to be able to execute an alternative debug command instead of the default one
• So that I can debug my app running in a different mode (different configuration, flags, etc..) and without modifying the default debug command.

This is similar to #5775, where I am able to execute an alternative run command instead of the default one.

Example:

SpringBoot devfile has the following default debug command.

- exec:
    commandLine: java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=${DEBUG_PORT},suspend=n
      -jar target/*.jar
    component: tools
    group:
      isDefault: true
      kind: debug
    workingDir: ${PROJECT_SOURCE}
  id: debug

In some situations, I want to run my Spring Boot application with a different profile.
This can be done by setting the spring.profiles.active=postgres JVM system property to the java command.

Currently, I have to edit the commandLine in order to be able to execute with a different profile.

Instead of that, it would be nice to be able to add an extra (non-default) debug command like this:

- exec:
    commandLine: java -Dspring.profiles.active=postgres -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=${DEBUG_PORT},suspend=n
      -jar target/*.jar
    component: tools
    group:
      isDefault: false
      kind: debug
    workingDir: ${PROJECT_SOURCE}
  id: debug-with-postgres

And then simply execute odo dev --debug --debug-command debug-with-postgres; when I want to switch back to using the default profile, I stop running odo dev command and start it again, but this time without --debug-command flag.

Acceptance Criteria

• odo dev should have --debug-command flag that controls what debug command is used to start the application in debug mode.
