Missing a cd command while generating configuration file and setup of environment variable.

[Rohini Choudhary]

In https://murano.readthedocs.org/en/stable-kilo/, there are some mistakes as below:

1. While installing the API service and Engine (https://murano.readthedocs.org/en/stable-kilo/install/index.html#installing-and-running-manually), Murano git repository is cloned. After that, sample configuration file is needed to generate using tox. It should be done inside murano repository cloned, but it is not mentioned in the documentation.

2. In Installing and Running the Development Version section (https://murano.readthedocs.org/en/stable-kilo/install/development.html):
a. While copying Murano integration scripts to Devstack, environment variables are used, but it is not mentioned to set them. Either it should be mentioned to set them, or it should be copied without using environmental variable.
b. To integrate murano with devstack, neutron additional service is required, which do not come by default with devstack. So, it should be mentioned explicitly.

    Add cd, export and enable service command in doc

    While installing the API service and Engine, sample configuration file
    is needed to generate inside murano/murano using tox. Hence add cd
    command.

    While installing and running murano with devstack, environment
    variable DEVSTACK_DIR is used. Add export command to set environment
    varible. Neutron additional service is also required by murano which
    do not come by default with devstack. It is mention and add command to
    enable it.
